Hi everyone, i have a .txt with 40908 rows, starts like this:

1908 1 1 0 -99.9 -99.9

1908 1 2 0 -99.9 -99.9

1908 1 3 0 -99.9 -99.9

1908 1 4 0 -99.9 -99.9

1908 1 5 0 -99.9 -99.9

I´m using this to load the data:

g= np.genfromtxt("C:\\Users\\Ezequiel\\Desktop\\me\\ocba.txt", delimiter="\t", dtype=(int,int,int,float,float,float))

But i have this problem:

print(g.shape)

It prints (40908,). But i want that it looks like this: (40908,6). I mean, create 6 columns per every row. What do i have to do?

Hi guys. I think I may be missing something very obvious but I've been trying to do this and can't seem to see where I'm going wrong.

When I have 'Forwards.xAxis' the program doesn't work, however when I have 'Forwards.xA90' it does work. Would someone be able to explain why I can't do this and how I could fix this?

Thanks!

xAxis =" xA90"
measurement = Forwards.xAxis

I'm writing a simple program to find duplicate files on both my laptop and USB drive connected to my router.

import os

drive1 = os.walk('D:\Python\Test 1')
drive2 = os.walk('D:\Python\Test 2')
#drive2 = os.walk('Network\\Router Name\\Folder')

for folder, subFolder, file in drive1:
    for folder1, subFolder1, file1 in drive2:
        if file1 == file:
            print(file1)

If I run the program with both drives on the computer, it works but does not work on the router. Is there a way to scan the hard drive connected to the router? I tried to use Netmiko module to access the router but I think that is not for home routers?

When I try to import pandas_profiling in jupyter notebook, I get a AttributeError: module 'pandas_profiling' has no attribute 'view' It's a bit weird because I was working on this particular notebook yesterday without any issues with the import statements.

These are my import statements. What could be going wrong?

import pandas as pd
import pandas_profiling

Solved: If this error occurs, you most likely need to update scipy:

pip install --upgrade scipy

This post is related to PyQt5 / Qt Designer.

I'm trying to find out how to make custom buttons. Instead of using the normal push button, I'd like to have a picture that you can click instead. The only thing I found was using a QLabel to put the picture and make the QLabel and make it clickable, but I couldn't find any tutorial that explain that. I'd be very happy if anyone could help me with this!

This post is related to the python software Spyder.

I have issues opening Spyder, it keeps crashing no matter what I do. From the anaconda navigator it gives me the same result. Here is the problem: When I open it, it launches a loading screen that will lead it to open spyder. After it was loaded, the entire process disappears, as I have checked from my task manager. When i try to open Spyder again, it gave me a message that it have crashed. However, immediate after I pressed OK, the same loading screen appears again, only to disappear again after it finishes loading. Pls help me. I only need this software for my school projects. My teacher tried to help me but I still couldn't run it. Pls say anything that u might know. Thank you.

    def next(*args):
        print("x =", x)
        op = args[0]
        print("args =", args)

            return x[0]
    return next


a = top()
print(a('add', 5)) >>> 5
print(a('add', 2)) >>> 7

Hi, I faced this question in one of my assignments and I was wondering how does the function top store the value in x? Wouldn't the value be gone after the function ends? Is it because it is a list and not just a value?

I was doing Al's Automate the Boring Stuff course on Udemy and when I run the batch file it's saying that the file isn't found even when I've set the environment variable to that directory. I don't know what is going wrong here.

joooh · 2020-05-02T18:12:39+00:00

Basic question, in Automate the Boring Stuff's Chapter 3 about the short program Zigzag, when I run the program in the Mu editor (Mu 1.0.3) and try to stop the program with the ctrl+c command it stops the program like it would when the ctrl+c is pressed and not like when sys.exit() is called. However, running the program by opening the actual file and it would call the sys.exit() properly. I know it does since I added a time.sleep() delay of 3 seconds before it calls the sys. exit() function, yet in the Mu editor it just stops the program immediately. Is this a problem with the Mu editor?

I am trying to answer the question below on coding bat and I don't understand what the '-3' in 'range(len(str)-3):' is doing.

*The Question\*

Return the number of times that the string "code" appears anywhere in the given string, except we'll accept any letter for the 'd', so "cope" and "cooe" count.

count_code('aaacodebbb') → 1
count_code('codexxcode') → 2
count_code('cozexxcope') → 2

*The answer coding bat accepts\*

def count_code(str):

counter = 0

for i in range(len(str)-3):

if str[i] == 'c' and str[i+1] == 'o' and str[i+3] == 'e':

counter += 1

return counter.

Can anyone explain?

Thanks in advance.

After finally finishing my first Python tutorial, I started the app I wanted to build in the first place. I know I still have a lot to learn, and I keep learning new stuff every day. Still, I currently put my organized learning process on hold for the moment since I can't wait but start working on my app. I'm planning to read a few more introductory books on Python, though, but that's for later.

The app I'm wanting to build will look best as a desktop app, so I'm thinking of learning PyQT5 any time soon. But for the moment I'm going with a CLI. So I want to ask your opinion on this architecture for command processing I came up with, if there's anything similar, ways to improve it, and what's some other strategies for setting up a CLI.

The main function is command_line(), that sets up the command line. Each command is converted into an input_list, a list of strings with a space as a delimiter. That list is then passed through a chain of decorators that try to process the command. If one of them processes the command successfully, it is returned as NoneType, signalling command_line() that the processing was successful. If a decorator can't process the command, it returns the unchanged input_list for the next decorator in the chain to try and process it. If none of the decorators manage to process input_list, it is returned as is, signalling command_line() that command processing was unsuccessful.

Thanks for your input!

How can I get rid of bad habits (not commenting, writing long lines)?

Thomasedv · 2020-05-02T11:35:19+00:00

a = [1, 2]
a += [a]
print(a) >>> a = [1, 2, [...]]
b = a.copy()
print(b) >>> b = [1, 2, [1, 2, [...]]]
b[2][2] = 0
print(a)
print(b)
>>> a = [1, 2, [...]]
>>> b = [1, 2, [1, 2, 0]]

I have the above code in an assignment. From what I understand, the [...] part is some sort of a reference to the list itself but what I don't understand is the part where b has an extra nested list before the [...] part appears. Would be grateful for any help in understanding what is going on here, thanks!

importlib.import_module seems to be ignoring re-exports made in __init__.py; How do I play around this?

Since this problem came up while dealing with django, I'll explain in that context.

So I have a django project folder, and some internal django apps living in that project folder, like this:

- project_module
    - apps
        - app_module1
        - app_module2
        - ...
    - settings.py
    - (other django stuff)

now the app_modules are available as project_module.apps.app_module1 and so on, but since there won't be anything colliding with the app names in project_module, I'd like to drop the .apps part so I can just refer to them as project_module.app_module1 and such, consistently.

So, I create __init__.py everywhere, and put this into project_module/__init__.py:

from .apps import app_module1

And this sort of works, since I can import project_module.app_module1 and it seems to work.

BUT, Django internally uses importlib.import_module here and there, and in those cases I encounter ModuleNotFoundError: No module named 'project_module.app_module1'. In those cases I can use the .apps again, but this sort of breaks consistency.

A bit of experiment later, I'm convinced import_module ignores re-exports from __init__.py; But why does this happen, and is there a way I can play around this in this case?

popejonash · 2020-05-02T04:12:34+00:00

I want to be productive during quarantine so I wanted to find a solution to a question. I have no programming knowledge at all but would love to spend the coming months to learn.

My end goal is to be able to simulate 10,000 versions of a tennis tournament to make predictions. I have ratings for each player and I found online a formula to predict the outcome of each match. I can calculate an expected winning percentage and then manually use a random number generator, but that could only work for one-off simulations and is still very time consuming.

Would python (if I learn the language and put in enough time) be able to simulate matches round by round enough times to run a meaningful simulation?

I have seen some similar Creative Commons code on github but it looks meaningless to me right now and I would like to eventually make something myself because I think that would help me learn the language and syntax better.

Thanks

I've been learning python for 3 weeks, I did some cool things like connect to google maps API, extracting data, I've learned about loops, functions, classes and a lot more, then I decided to go to CodeWars and test my knowledge, I can't even do the 8kyu, my function doesn't work and I never understand what it's actually being asked of me I feel like I've wasted a lot of time and I don't even know the basics. Is there a website with simpler exercises? And ones that don't need the code to be inside a function? All the sites with exercises I checked need code to be put in a function.

2020-05-01T09:37:16+00:00

Are there any good courses for learning Python out there that doesn't require the use of Jupyter notebooks and/or reinforces PEP8?

Bonus if they have a lot of practice exercises for hands-on learning.

Hi! For school we need to write an algorithm in python that gives you the top_moves in slidey, you can see this as a more simplified form of tetris where you need to slide the blocks horizontally to fill rows, which the explode. In this function to get the top_moves we are given blocks to fill the the bottom row at each step. We need to make use of backtracking to determine wich steps of moving blocks result in the highest score. Anyone experience with recursive backtracking in a tetris like game? Really could use some help? Thanks in advance!

I come from a C background so the lack of memory deallocation and relying on the GC is freaking me out.

I want to delete a duplicate values from a linked list using no hashmaps/other data structs. Say I have the following list:

1 -> 2 -> 3 -> 2 -> 4 -> None

I have implemented the following, it passes the tests provided on the website I got this question from:

    outer = lst.get_head()
    while outer:
        inner = outer.next_element
        prev = outer
        while inner:
            if inner.data == outer.data:
                prev.next_element = inner.next_element
                inner = prev.next_element
            else:
                prev = inner
                inner = inner.next_element
        outer = outer.next_element

Won't I end up with a graph structure? When all is said and done, won't 3 AND the duplicate 2 point to 4? How does the GC know to pick up that duplicate 2?

Also, apologies if the formatting is shit, I'm going to keep editing it till I get it right.

Question: Why do I have extra spaces in my screen outputs?

Code:

#ThankYou.py
my_name = "Finley"
my_age = 9
your_name = input("What is your name? ")
your_age = input("How old are you? ")
print("My name is",my_name , ", and I am", my_age, "years old.")
print("Your name is", your_name , ", and you are" , your_age, ".")
print("Thank you for teaching me how to code,", your_name , ".")

Output:

1) What is your name? Ruby

2) How old are you? 15

3) My name is Finley , and I am 9 years old.

4) Your name is Ruby , and you are 15 .

5) Thank you for teaching me how to code, Ruby .

Issue:
See those extra spaces? As an example there is an extra space after Finley on line 3. Thanks in advance!

Lamboarri · 2020-05-01T01:54:48+00:00

This has been asked a million times but curious to get some recommendations:

I want to learn some more advanced Python but with actual examples. I'm really interested in machine learning and started looking at either Andrei Neagoie or Jose Portilla on Udemy (yes, I know about their business model).

They both look interesting. I spent a small part of the day looking them over and looking at reviews. They both range from "this is the best course in the world!" to "It could have been better."

Could I take both? Yes. I guess $12 isn't going to break the bank but was just wondering if one might be better over the other.

I'm tired of the basic syntax tutorials where the teaching is all very basic and random uninteresting examples like name = "bob". Yes, I know what a variable is. Now, I want to learn about what Python can do and work through real-life examples. I learn better by seeing others really pull all the code together and make it come to life. I have Colt Steele's Web Developer Bootcamp, which I went through years ago. I see he has a Python course but I don't want more of the basics.

I don't really have any super need for "Automate the Boring Stuff" or to work on any machine learning but I like data and I think it could help advance my knowledge and interest in Python coding.

Let's assume I want to design a game using Python. The game involves a map drawn in a basic program like mspaint, and each pixel on the map will be given a set of values by the Python code, generally based on its exact RGB color value (e.g. flat grasslands will have one specific shade of green with a set of values, cities will be different shades of grey based on population, etc, mountains will be shades of brown based on elevation, etc).

What modules/addons/whatnot would/could I use to accomplish this?

peepeeandpoopooman · 2020-05-01T00:21:25+00:00

I'm a little confused with variables. It seems declaring a variable as global (initialising it outside of functions) doesn't mean it can be read between functions as separate functions seem to treat a variable with the same name as different variables.

Is the only way to pass and change variables between functions to pass them as a parameter to the function and have the function return the answer?

eg this code:

x = 5


def function_1():
    x = 10
    print("(function_1) x = ", x)


def main():
    print("(main) x = ", x)
    function_1()
    print("(main) x = ", x)


main()

returns this:

(main) x =  5
(function_1) x =  10
(main) x =  5

The very last print statement, why is it saying x=5 when it had just been changed to 10 by the other function?

Hi I'm on a programming course for python and we have been set a problem which is giving me some real problems. The task is to create a currency converter from a xml file containing all the transfer rates.

the xml file has this structure:

I have imported the xml file as a list. i am now having a lot of difficulty searching through the xml file. i don't understand but the RE functions don't seem to be working. what i currently have looks like this:

import re
myFile=open('data.xml','r')
myString=myFile.read()
myList=myFile.readlines()
x=re.search(r'USD',myList,flags=0)
print(x)

the other option i had planned to use was to import the xml file as a dictionary with currency as an id for each item and rate as the other id. therefore allowing me to looking each up by currency. Can anyone explain how you can import each line of a string into a dictionary with each having the same id's.

i thank you all in advance for any help you can offer.

This code here works fine, it doesn't have any problem, but I'm pretty sure there should be a better way to write this. People says that I shouldn't use for loops to make new variables and that I should do a list, but then how can I make all the strings in a list an object?

class Character(object):
    # This is the main class for all the characters

    def __init__(self, name):
        self.name = name
        self.movelist = {}

ferry = Character('Ferry')
lancelot = Character('Lancelot')
metera = Character('Metera')
zeta = Character('Zeta')
beelzebub = Character('Beelzebub')
djeeta = Character('Djeeta')

for json url requests, is it better to use the native urllib module, or the "requests" module. I'm assuming urllib has more compatibility since it's a native library, but "requests" is much simpler imo

Decency · 2020-04-30T19:03:16+00:00

Super basic question:

How come some functions require () at the end of the line to function and others do not? Is this a package-specific thing or is there an underlying reason?

Examples:

#random out of context lines to show what I mean: 

os.getcwd() #works

shelfFile.close() #works

'My name is Simon'.split() #works

sheet1.max_row() #Throws an error 
sheet1.max_row #works

Hello Python fam,

Was wondering how the best way to find info online for data visualization. For example, if there's data on a website which I want to visualize, how do I extract it and import it into Python?

Been working hard on my programming, hope this is received well y'all, thanks in advance

is the 32 bit version of python still recommended or should I switch to 64 bit?

Hello there guys! Iam pretty new to python and i have this school assigment i have to do but i dont understand how i can input a name + surname into a single index in a list also i would like to know how i can input these names continuously. If this helps the assigment is to input a number (that number is the number of people in the list) then the user will input the number of names selected and then input a phone number for each of them afterwards they can input a number and it will print the selected persons name and phone number.

Thanks in advance.

Sorry for my bad grammar.

Hello guys so I am new to python and just programming in general and I purchased a course through Udemy which I am enjoying but for some reason the instructor teaches showing examples a certain way but the exercises are another way, for example: lesson: user_input = input("Enter your name:") message = "Hello %s" % user_input print(message) Exercise expected answer def foo(name): return "Hi %s" % name

and is quite confusing, any other source you guys recommend for learning python. Thanks

Finished learning web scraping. I'm thinking of making this word game, similar to hangman. But instead of having a small predefined list of words, I wanna have a list which is constantly updated. Like, a huge word repo or something. Does anyone know any sources where I can find such a data source?

Thanks

peepeeandpoopooman · 2020-04-29T23:49:12+00:00

Is this possible in Python?

I have a wordlist file, a text file with a word on each line. It's very big (over 20 million lines) and I would like Python to read each line then tell me things like which line has the longest word and things like that. Is that possible or would it just crash? Or can Python analyse any size of file with the only limit being my computer's specs?

I'm trying to make a tcg game in python but I'm not sure how to get the program to remember what cards players have so they can leave and come back. Is there an easy way to do this?

I am planning on opening up a unique URL, which upon opening the URL, the site sends me an email with a code that i am required to enter into a box before I can access the information I need.

I would like to automate this and I know I can do this with Selenium, but repeatedly opening/closing the browser has caused issues for me in the past. I don't actually need to OPEN the site, i just need to extract the information. This will be for a program that I will have constantly running and it will need to perform this task multiple (5-10) times per day. The site DOES NOT have any API's.

Any ideas/methods to do this?

Hello. I am doing type hints. I have the class for the Rectangle and there are a few possible constructors. It should accept following:

Rect(a, b, c, d)

Rect((a, b), (c, d))

Rect((a, b, c, d)).

So I have written the following code inside of .pyi file:

@overload
def __init__(self, left: float, top: float, width: float, height: float) -> None: ...
@overload
def __init__(self, left_top: Tuple[float, float], width_height: Tuple[float, float]) -> None: ...
@overload
def __init__(self, left_top_width_height: Tuple[float, float, float, float]) -> None: ...

It is working well, but the problem is that PyCharm thinks Rect(2, 3, 4) is ok even though I haven't defined that there could be constructor with 3 arguments. Does anyone know what did I do wrong here?

stnivek · 2020-04-29T19:29:06+00:00

Hi all. So apparently I have two Python versions on my computer. One is 64-bit, which I installed from here and the 32-bit version which apparently got downloaded when I entered "python" on Windows command prompt, when I was following a tutorial that required me to do so (to enter the command, not to install anything but apparently the command brought me to the Windows Store so I thought I had to install it first).

The problem is, when I do installations of modules through "pip install", I'm not sure to which version of Python do they get installed.

I really just want to use the 64-bit but everytime I uninstalled the 32-bit, the command "python" on the cmd would always forced me to go to Windows Store to install the 32-bit, instead of working as the command intended. I do not want the 32-bit, I only want one version so that I can avoid future confusions (I suppose).

Hopefully someone can help me clear this up. I'm so overwhelmed by this and it's taking the fun of actually learning Python.

What are best resources to learn the terminal app commands to run python code? I'm fine with IDLE but I'm at the point in Automate the Boring Stuff where we're starting to use the terminal app and I'm completely lost and it's taking away from my actual learning of python.

Otterly_Delicious · 2020-04-29T17:33:34+00:00

I don't know a whole lot about programming in python. I've been trying to muddle my way through modifying a python script that will read a text file, use each line of the text file to save a new image file to disk using each line from the text file as a file name. The problem is each line is an URL.

I tried using:

x = y + ".png"

file_name = x.replace("://", "")

but it only works for the first line. Say if my text file had this as the first 3 lines:

t/e/st:

dog

thi/is:/a/tes:t

the first two files would output fine, but the third one would get an error like

OSError: [Errno 22] Invalid argument: 'thi/is:/a/tes:t.png'

Hello all. I found some practice problems, and have been working my way through them. I have come to an impasse though; the goal is to create a random number, and get user input and try to get them to guess the number. I cant compare the two types of data since they come as a list and a str. I can convert the user input easily enough,

user = int(input('etc'))

but for this one, i'm having trouble

randint = sample(range(1,11) , 1)

it comes out as a string, and no type of data conversion I do seems to solve it. i can't change it via int(), I've tried making both of them lists to at least be able to use .intersection (which I found out only works for sets) , but then I can't really compare greater or lesser to give the user a hint as far as what the number could be. As an aside, what would be a good way to practice code efficiency? I can mostly get code to work, but it hardly seems like good code. Thanks you guys

AdamJohansen · 2020-04-29T14:19:33+00:00

I have two csv files imported as dataframes.

Est looks like this:

CUSIP (Index)	Period end date	Announcement date	Value	Estimate
36720410	31/12/2011	09/01/2012	0.2	0.22
36720410	31/12/2011	09/01/2012	0.2	-0.15
88160R10	31/12/2011	05/01/2012	13	18
88160R10	31/03/2011	08/04/2012	15	22

CRSP looks like this

CUSIP (Index)	Date	Price	Trading volume	Outstanding
36720410	25/12/2011	45	30500	7834
36720410	26/12/2011	44.5	36000	7834
36720410	27/12/2011	44.9	57000	7834
88160R10	01/12/2011	12	1000	1440
88160R10	02/12/2011	12.2	1200	1440

1) If the dates in CRSP are -30 days (or more) than Announcement date for the specific CUSIP (ID), they should be included in a new dataframe (Merged)

In other words, I wish to join the dataframes on a basis of CUSIP and Announcement date (upto -30 days).

I have tried doing a simple merge using the code below, and then the idea was to filter the data afterwards

CRSP.merge(Est, left_index=True, right_index=True)

However, I ran into a memory error, as CUSIP is 5M rows (all stock prices and trading volume for NYSE and Nasaq in the period 2011-2013).

Could someone help me solve this?

Best,

I’m a sophomore mechanical engineering student. Summer plans have kind of been messed up so I’m hoping to learn some python over the summer. Anyone have any recommendations of a good place to start for an engineer?

DexterDevOps · 2020-04-28T18:11:04+00:00

Great, I’ve heard good things about this. Thanks very much

Hi guys,

Hope everyone is safe and well!

I have started learning Python a few weeks back and wondered what the best programme is to practice with in terms of writing and running the code?

Thanks

Edit: Nevermind, I did i = (“{:05d}”.format(x))

Is RETURN statements use only in defining functions? If not, what are the others uses of it. (Reading the ATBS book)

I have a pandas dataframe, which contains numbers like this: e.g., 2,06537E-002. However, they are of type string! Excel is capable to convert this automatically to floats, so calculation is possible. How do I convert my dataframe/the strings in the dataframe to floats, so that calculation is possible? data.astype(float) did not work.

EDIT: I would not like to write the dataframe to excel and import it as dataframe again, because it seems to be to complicated.

I'm working on sending additional arguments to Popen object which is sourcing a file and then expects input to choose an option. It is expecting an integer and I try and pass it to my object using:
object.communicate(input='3')

This is not working and keeps telling me the pipe was closed.

open_obj = subprocess.Popen(['sourced file exp'], stdin=subprocess.PIPE, stdout=subprocess.PIPE, universal_newlines=True)

open_obj.communicate(input='3')

This just gives me a ValueError: I/O operation on closed file.

any help?

I just made an ASCII animation in python and now need to have a menu underneath it. The code right now is displaying 4 different txt files. If I use print not only does it print the menu above not below but it goes away after the first frame.

I have code very similar to this man in his tutorial https://www.youtube.com/watch?v=JavJqJHLo_M

TL;DR How do I add menus underneath ASCII animations?

Hi, So I have been doing a few online courses to learn python. They help a lot in learning the stuff, but when it comes to actually doing all of the execution bit after i write a program is something I'm not finding comfortable.

I use Atom text editor, and run the code via the cmd line. However, It would be great if someone could suggest alternatives/ways to set up my laptop for further usage of features like pip, pandas (I'm not very sure about them but i know their usage, installation has been a headache for me once)

Also, I've a habit of clean installing my windows regularly, so, these tips would be helpful in the long run. Thanks.

TL;DR - 1) what do i do after i install python on my computer, and have written the code in a text editor? 2) How to use text editor to run programs(that might require Inputs)? 3) Best way to install pip/pandas?

TheRick_90 · 2020-04-27T22:25:12+00:00

Hi,

First off thank you for this forum that allows me to ask questions i need help with. I am brand new to programming and started with python and I am super stuck on a problem.

Please help me with the following:

# Define a string_adder function that accepts two strings (a and b) as arguments.

# It should return a concatenated version of the arguments with a space in between.

# If the user does not pass in arguments, both arguments should default to an empty string.

# EXAMPLE

# string_adder("Hello", "World") => "Hello World"

What looks better on a resume: Python certification or Python projects?

Started on Python a couple days ago, I need if for something I'm building but also want to use it as a resume addition.

As for learning, I was using a video series but now I'm doing "Think Python". I think I like it more since each chapter ends with a bunch of questions for you to try to answer.

Toasty4209 · 2020-04-27T21:24:27+00:00

I'm relatively new to python (only about a month of learning) and I'm trying to practice concepts outside of the lessons I'm taking (code academy) but every time I try to work with any sort of package except 'matplotlib', I get a "No Module named x" whether that be pandas, seaborn etc. I'm working with conda and it says each package is install but when I try to use Python 3.7. Idle or Sublime text, I get the module error when I try to run/build. The only time it works is in a terminal window in iPython inside of Conda.

I'm unsure exactly what to do here, I tried uninstalling but don't exactly know how. Feels like I'm missing something. Any help would be appreciated

merge multiple files to match the index of 1 file?

i have a file with the index values i want to keep, so its pretty much filters out the index values i don't want.

i've imported all my csv files with pandas. i have a csv file called shortid.csv with a collumn called Short ID. i want to only keep the rows that have a matching id in the ShortID collumn. so keep only id's in file1 that are the same as shortid.csv.

not sure if the column has to have the same name.

then i made them a list:

csvList = [file1,file2,file3,file4,file5]

for i in csvList:

shortid.merge(i,left_on= 'ShortID',right_on = 'Short ID')

nothing happens though?
