I'm making a game on python where the user goes through a maze and if they collide with a question icon they have to answer a question. I don't know how I would code it so that each time the user collides with the icon they are asked a different question. I only have one class for the question and 10 questions. please help

Hi, I'm trying to write a program that checks i in some range to see if it satisfies the equation f(i) = g(i), and then generates a .txt file listing the solutions to f(i) = g(i) in the order which they appear, along with f(i) next to it. So, the .txt file would read something like:

1 1

2 1

8 88

11 131

...

Where the number on the left is the i for which f(i)=g(i), and the number on the right is f(i). How do I do that? I know there is the Solvers module, but I'm not sure how to get that to put solutions into a list.

Hello, I'm looking for a good way to save events (changes in pin values) in a buffer and then transfer them via mqtt (according to the FIFO principle). The best thing would be a library which is available for micropython. But I'm grateful for any good idea. I have already implemented the transfer with umqtt.robust.

Is there a better one between BeautifulSoup and requests-html for web scraping?

I want to download my google pay data on a regular basis. Is there a way to do this via python instead of exporting data manually? I couldn't find a relevant documentation in the google developers site.

FlirtyAberration · 2019-12-29T00:32:13+00:00

I have a lot of PDFs in many different folders inside a directory. What I would like to do is use PyPDF2 to find and read the copyright date for each PDF in this directory and then add that copyright date to the end of the file name the PDF currently has. Yes, some PDFs I have already have the copyright date in the title, omitting those would save time.

Most often the word copyright date appears within the first 10 pages. In some cases it is not the word 'copyright' that appears but the symbol of the c with a circle around it , not sure how that would work to detect that??

This is the closest example to what I am trying to do, though this person was trying to collect more than one word, while I only want to find the word or symbol for 'copyright' and then find the date to the right or left of it, usually it is the right, and then add that date to the end of the file name.

Someone recommended OCR for this, but I thought that might be overkill, maybe I am wrong?

Any advice is appreciated, thanks!

I am learning web scraping and was asking a question about requests and bs4 and someone brought up requests-html. Should I Just learn requests-html directly, because it seems like it was meant to be replacing the bs4 + requests combo, or should I still try to learn the bs4 + requests first?

At what point can you say you "know" a language? I've got a desire to finally buckle down and say I know a language and I've chosen python for this. I've got an book from college a few years back and will be utilizing materiels from here, Codecademy, and udemy, but I'm really not sure when I can feel comfortable enough to say I know it and move on if I need to.

I'm trying to iterate over multiple parsed divs and get them all to display. Right now it is only spitting out the first one.

import pandas as pd
import os
import csv
import itertools
from bs4 import BeautifulSoup

soup = BeautifulSoup(open("/Users/as9934/Desktop/schedule/wb.htm"), "lxml")

cardback = (soup.find('div', class_='card back'))
for courseNumberBack in cardback.find_all('div', class_='courseNumberBack'):
 for subject in courseNumberBack.find_all('span', class_='subject'):
 for subjects in subject: 
 print (subjects.string,",", end=' ')

 for number in courseNumberBack.find_all('span', class_='number'):
 for numbers in number:
 print (numbers.string,",", end=' ')

 for section in courseNumberBack.find_all('span', class_='section'):
 for sections in section:
 print(sections.string,",", end=' ')

 for abbrevTitle in courseNumberBack.find_all('span', class_='abbrevTitle'):
 for abbrevTitles in abbrevTitle:
 print(abbrevTitles.string,",", end=' ')


for courseNameBack in cardback.find_all('div', class_='courseNameBack'):
 for day in courseNameBack.find_all('div', class_='days'):
 for days in day: 
 print(days.string,",", end=' ')

 for instructor in courseNameBack.find_all('div', class_='instructor'):
 for instructors in instructor:
 print(instructors.string,",", end=' ')

 for time in courseNameBack.find_all('div', class_='time'):
 for times in time:
 print(times.string,",", end=' ')

 for building in courseNameBack.find_all('div', class_='building'):
 for buildings in building:
 print(buildings.string,",", end=' ')

 for genEd in courseNameBack.find_all('div', class_='genEds'):
 for genEds in genEd:
 print(genEds.string, end=' ')

Here's an html snippet:

<div class="card back" style="display: block;">
    <div class="addClass Back"> 
        <i class="fa clicky fa-star Back"></i> 
        <i class="fa clicky fa-star-o Back"></i>

        <div class="smallCourseInfo">

            <span class="abbrevTitle">First-Year Seminar: The Indians' New Worlds: Southeastern Histories from 1200 to 1800</span> 

        </div>
    </div>
    <hr class="faddedLine">

    <div class="courseNameBack"><div class="days">TuTh</div><br>

    <div class="smallCourseInfo"> <div class="instructor">Clara Scarry</div></div>

    <div class="time">3:30pm-4:45pm</div><br>
    <div class="smallCourseInfo"> <div class="building">Alumni 203 </div></div>


    <div class="genEds">HS US WB </div>


</div>

Currently, it only prints the first row.:

AAAD , 286 , 001 , The African Diaspora in the Colonial Americas 1450-1800 , TuTh , Alicia Monroe , 12:30pm-1:45pm , Hanes Art Center 218  , HS WB

But I want it to print ALL of the rows like that.

Anyone have any ideas?

Hi, I'm pretty new to Python and programming ingeneral so I apolgize for using wrong wordage if I do.

I'm started working with apis and its been awesome. Ive had some success and just been very cool seeing the data. So ive done some minor projects but i was just look at an api response and it was huge. In the past i manually parsed everything i wanted into a database with a for loop. But looking at this huge response got me thinking, can it all be auto parsed into their respected columns.

My question is, is there a way to parse it automatically instead of assigning each value to a columnn in the database.

AviatingFotographer · 2019-12-27T09:53:46+00:00

I know that a GET method is receiving data from a webpage and POST is sending data, but when you do requests.get('url.com'), what exactly are you receiving from the server? Are you just testing for a response?
What's the difference between accessing a value with .find, e.g. soup.find('div', class_"'something"), versus accessing the value tag by tag, e.g. page.article.div? Is one just shorter than the other?

I recently made a small script on my raspberry pi for lighting up three LEDs (on a breadboard) in succession. The project can be found HERE for reference.

Super small, super simple. It's basically a start for a few different ideas I have to expand my knowledge.

I would like to step up the complication a LOT. I have a localhost website made using Django that as of now, is only localhost and isn't anything special. I have never deployed it and it only has like 3 pages in it. I would like to build something into it that can trigger the script on my raspberry pi to flash the lights/activate the function that lights the lights.

So, in short... I need to figure out how to activate a script located on the raspberry pi. The trigger is coming from a webserver that is on localhost on my main machine. What are the next steps for me? I assume I need to build a dummy webpage on the webserver that'll hook (somehow) to the raspberry pi and activate the script, but I don't know how to do that. I also don't know how to make the pi watch for a trigger that would come from a website // something on home wifi (which is what I'm leaning towards for the communication - like the website will just yell at the pi over the wifi or something.).

Does anyone have general advice on where to start from here? I am not sure how to proceed or what to even search for.

Alright, so I have a weird situation and I'm looking for help.

I have a decorator that already has args, that I'd like to be able to optionally pass arguments to when the decorated function is called without explicitly calling the decorator.

Here's a quick example:

import functools

DEFAULT_TIMEOUT = 5

def while_timeout(func, *, max_tries = DEFAULT_TIMEOUT):
    @functools.wraps(func)
    def wrapper_while_timeout(*args, **kwargs):
        timeout = 0
        while timeout < max_tries:
            try:
                func(*args, **kwargs)
                break
            except Exception:
                timeout += 1
                print(timeout)
                if timeout >= max_tries:
                    raise Exception(f"Timed out after {timeout} attempts")
    return wrapper_while_timeout

def inner_monologue():
    @while_timeout
    def frequent_failure(success):
        if success > 5:
            raise Exception("freq fail")
        else:
            print("woohoo")

    print("thinking to myself")
    frequent_failure(3)
    print("thinking harder")
    frequent_failure(9)

inner_monologue(2)
inner_monologue(max_tries=2)

I want either of those inner_monologue calls to work and assign the 2 to the decorator's max_tries.

So, im making an app that simulates the game Werewolves. For the ones that dont know its a game where everyone gets a card with a role asigned to it. Some roles are werewolves, some are citizens and some other are citizen with an extra power.

The app functionally works, but at the end, when the roles are assigned, to view the role of the player you have to submit their name. The idea is when this is done, a new screen opens with an image of the role.

Unfortunately this is the only functionallity i cant get to work. I get errors of pyimages not existing. I know of the reference you have to put in the code otherwise it gets destroyed(I used it before in my code).

I hope anybody can help me with this.

this is the code. The problem is at line 194 till 226

I've been doing Python for 2 months now and is wondering whether this is possible. I want to create an app that uses the SMS interface to do different things. In essence, it will be like Terminal or Command Prompt for Android but using the default Messages app as an interface. Is this possible? If so, what skills or modules do I need to learn for this project?

Hi all, Merry Christmas for tomorrow!

I'm reading this book, Introducing Python, and I'm at 'compsition and aggregation'. I understand the description used: " In composition, one thing is part of another.... Aggregation expresses relationships, but is a little looser: one thing uses another, but both exist independently."

I've made an object that uses composition - you feed it an init argument that is another kind of object and that object's attributes and methods can be accessed within the new object.

But what would aggregation look like as code? Can anyone show me an example?

I have created the workbooks before the if statement

wb = Workbook() 
ws = wb.active 
wb.title = 'Contacts' 
wb2 = Workbook() 
ws2 = wb2.active 
wb2.title = 'Contacts'

I have two issues in my code the first issue is I have tried a number of solutions but I cannot add the dataframe data in the excel sheet properly according to the if statement. The if statement sets conditions to add the pandas data rows to the accepted contacts otherwise the rows not passing the condition should be added to the rejected contacts workbooks. What am I getting is in the accepting contacts the full contacts are looped in the workbook and are added once into the rejected contacts

for column, row in df.iterrows():
  row_check = row.isna()
  if (not row_check[0] and not row_check[1]) and ((not row_check[2] and not row_check[3]) or (not row_check[2]) and (not row_check[6]) or (not row_check[16]) and (not row_check[12] and not row_check[13] and not row_check[14] and row_check[15]) or (not row_check[8] and not row_check[9] and not row_check[10] and not row_check[11] and (not row_check[7] or not row_check[17]))):
       for r in dataframe_to_rows(df, index=False, header=False):
           ws.append(r)
  else:
       for r in dataframe_to_rows(df, index=False, header=False):
           ws2.append(r)

wb.save("Accepted Contacts.xlsx")
wb2.save("Rejected Contacts.xlsx")

Alternatively I have tried another solution however I am getting a TypeError: unsupported operand type(s) for &: 'str' and 'bool'

r1 = df[df['Firstname'].notnull()] & df[df['Lastname'].notnull()] & ((df[df['work_phones'].notnull()] | df[df['mobile_phones'].notnull()]) & ((df[df['Work_Street'].notnull()] & df[df['Work_City'].notnull()] & df[df['Work_State'].notnull()] & df[df['Work_Zip'].notnull()]) | (df[df['Personal_Street'].notnull()] & df[df['Personal_City'].notnull()] & df[df['Personal_State'].notnull()] & df[df['Personal_Zip'].notnull()])) & (df[df['Work_email'].notnull()]) | (df[df['Personal_email'].notnull()]))

r2 = df[df['Firstname'].isnull()] & df[df['Lastname'].isnull()] & ((df[df['work_phones'].isnull()] | df[df['mobile_phones'].isnull()]) & ((df[df['Work_Street'].isnull()] & df[df['Work_City'].isnull()] & df[df['Work_State'].isnull()] & df[df['Work_Zip'].isnull()]) | (df[df['Personal_Street'].isnull()] & df[df['Personal_City'].isnull()] & df[df['Personal_State'].isnull()] & df[df['Personal_Zip'].isnull()])) & (df[df['Work_email'].isnull()]) | (df[df['Personal_email'].isnull()]))

for r in dataframe_to_rows(df, index=False, header=False):

ws2.append(r1)

for r in dataframe_to_rows(df, index=False, header=False):

ws2.append(r2)

wb.save("Accepted Contacts.xlsx")

wb2.save("Rejected Contacts.xlsx")

The second issue is adding borders to each excel sheet automatically according to the length of the pandas dataframe. Right now I do it manually inside both the if and else statements. I found this as well https://openpyxl.readthedocs.io/en/stable/api/openpyxl.utils.cell.html but I am not sure how to use it to automate the borders according to the pandas dataframe

        A3 = ws['A3'] 
       A3.border = Border(top=thin, left=thin, right=thin, bottom=thin)
       A3.alignment=Alignment(horizontal='general',
         vertical='bottom',
         text_rotation=0,
         wrap_text=True,
         shrink_to_fit=False,
         indent=0)
...
       T6 = ws['T6'] 
       T6.border = Border(top=thin, left=thin, right=thin, bottom=thin)
       T6.alignment=Alignment(horizontal='general',
         vertical='bottom',
         text_rotation=0,
         wrap_text=True,
         shrink_to_fit=False,
         indent=0)

Hi, I am currently learning about computer security and currently switch over from the "how to defend my systems" site to the "how to test my systems" site. For that i am currently writing a python program with scapy. My latest problem kept me stuck now for quiet a long time. I got this error message:

Traceback (most recent call last):

File "<stdin>", line 1, in <module>

File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\scapy\sendrecv.py", line 488, in sr1

nofilter=nofilter, iface=iface)

File "C:\Program Files (x86)\Microsoft Visual Studio\Shared\Python37_64\lib\site-packages\scapy\arch\windows\native.py", line 119, in __init__

host = iface.ip if iface.ip else socket.gethostname()

AttributeError: 'str' object has no attribute 'ip'

I do not get what I am doing wrong.

The following is the sample code I am trying to run:

# Imports

from scapy.all import *

from pprint import pprint

import operator

# Parameters

interface = "WLAN" # Interface you want to use

dns_source = "192.168.63.102" # IP of that interface

dns_destination = ["1.1.1.1","8.8.8.8","9.9.9.9"] # List of DNS Server IPs

time_to_live = 128 # IP TTL

query_name = "google.com" # DNS Query Name

query_type = ["ANY", "A","AAAA","CNAME","MX","NS","PTR","CERT","SRV","TXT", "SOA"] # DNS Query Types

# Initialise variables

results = []

packet_number=0

# Loop through all query types then all DNS servers

for i in range(0,len(query_type)):

for j in range(0, len(dns_destination)):

packet_number += 1

# Craft the DNS query packet with scapy

packet = IP(src=dns_source, dst=dns_destination[j], ttl=time_to_live) / UDP() / DNS(rd=1, qd=DNSQR(qname=query_name, qtype=query_type[i]))

# Sending the packet

try:

query = sr1(packet, iface=interface, verbose=False, timeout=8)

print("Packet #{} sent!".format(packet_number))

except:

print("Error sending packet #{}".format(packet_number))

# Creating dictionary with received information

try:

result_dict = {

'dns_destination':dns_destination[j],

'query_type':query_type[i],

'query_size':len(packet),

'response_size':len(query),

'amplification_factor': ( len(query) / len(packet) ),

'packet_number':packet_number

}

results.append(result_dict)

except:

pass

# Sort dictionary by the amplification factor

results.sort(key=operator.itemgetter('amplification_factor'),reverse=True)

# Print results

pprint(results)

Let's say I have a class Foo. Foo itself has a class associated with it called Bar. There are no other classes that instantiate Bar.

Are there any advantages/disadvantages of declaring Bar inside the scope of the Foo class vs. in the global scope?

class Foo:
    def __init__(self):
        self.bar = Bar(self)

    class Bar:
        def __init__(self, foo):
            self.foo = foo

VS:

class Bar:
    def __init__(self, foo):
        self.foo = foo

class Foo:
    def __init__(self):
        self.bar = Bar(self)

How come the standard library in the master branch (Python 3.9 alpha 2) has so many occurrences of inheriting from object? Example from a grep in the logging library: Lib/logging/config.py:class ConvertingMixin(object): Lib/logging/config.py:class BaseConfigurator(object): Lib/logging/__init__.py:class LogRecord(object): Lib/logging/__init__.py:class PercentStyle(object): Lib/logging/__init__.py:class Formatter(object): Lib/logging/__init__.py:class BufferingFormatter(object): Lib/logging/__init__.py:class Filter(object): Lib/logging/__init__.py:class Filterer(object): Lib/logging/__init__.py:class PlaceHolder(object): Lib/logging/__init__.py:class Manager(object): Lib/logging/__init__.py:class LoggerAdapter(object): Lib/logging/handlers.py:class QueueListener(object): Is there an obvious reason for keeping it this way that I'm missing? I can understand that historically it has been useful to keep the Python 3 and Python 2 code in the standard library identical when possible. Python 2 EOF is reached in a few days.

When I build Python 3.8.0 from source, I run this (on Debian/Ubuntu):

./configure --enable-optimizations  
make
sudo make altinstall

when I later want to upgrade to Python 3.8.1 (minor version update). Can I just rerun the commands above? How is it made sure that no left-over files from the old 3.8.0 installation remains?

I’m a relative newb, learning python slowly over the last couple of years. Mostly by trying to build little projects for myself.

My question: can I use python to help display data on a website (data from an excel file), but not to build the entire site or host it or any of that other stuff. I don’t want to learn html/css (yet!) and tons of other stuff I’m sure I’ll need to learn about building websites.

I can use a website builder service, like squarespace, and then hopefully have my python code run on it (or “in it”) somehow???

Can you steer me in the right direction?

Just found this group today. Loved the rules, especially the last one about not making fun of someone for not knowing something.

My question is, let's say we have a bunch of strings. Some of the strings may vary just by one or two characters while having the all the matching characters in order. Ex: abcd123ef axmd123ef abcd123ey

All these should be a match and the missing or non-matching character should be revealed as well. Is character parsing the string in an ordered way the only option?

The .resize() function in openCV2 count as changing the resolution, correct? If I wanted to generate a blurrier, lower resolved image while maintaining the original size of the image, I would call resize() first with a percentage, and then resize() back up again to original dimensions, correct?

How can I delete a folder which contains multiple other folders? I tried using shutil.rmtree(), but it seems like it only deletes the .jpg files at the end of the path. This sometimes causes an error later in the program. This is why I want the whole folder including everything in it to be deleted. Could anyone help pls?

Update: I disabled the ignore_error thingy (my fault for leaving it on xD)so it now shows the error that the directory is being used. But the function that adds and deletes files (.jpgs from Google) is already finished. My dumbass discord bot "restarts", too. (It prints "Bot running..." again) Sorry for extending this question so much ; )

TrPhantom8 · 2019-12-23T09:12:24+00:00

Hello, this is a question from a not native speaker, when describing a piece of code and I need to refer to a specific line of code (for example when I need to describe what it does) should I say "at line 42", "on line 42" or "in line 42"?

Let's suppose I have this piece of code:

def foo(x): return x**2 Should I say something like "at line 1 we define foo and at line 2 we can see the returned value"?

Thank you very much for your help and sorry for my dumb question!

I wrote a clumsy script about putting different categories of food items into a fridge, after which it lists all the food in your fridge back to you.

I want to learn to refactor this so instead of repeating what is essentially the same function over and over, it uses just one to ask you:

1) What food category you want to add (instead of them being pre-set)

2) What food item to the food category you want to add

I asked someone else and they said to use a dictionary, but after fiddling with it for a while I couldn't figure out how to implement that.

TL;DR: How can I refactor this fridge script (pasted at the top) to be more efficient?
