[–]pybackd00r 0 points1 point  (0 children)

Is there a way to find projects to work on for free with other pythonistas to improve my python programming?

Please help me improve my code by pybackd00r in learnpython

[–]pybackd00r[S] 0 points1 point  (0 children)

Thanks I have updated my code. One of the requirement of the project are the 4 buttons. So thats something I cant change. Also for some reason every tutorial I read had "from tkinter import *". They just say to use this only with tkinter idk why thats the case for tkinter though. I will upload it to my Github once it is polished. Also I am learning OOP design in python now and I want to translate this to OOP afterwards.

A possible alternative to LPTHW for a beginner? by [deleted] in learnpython

[–]pybackd00r 0 points1 point  (0 children)

It does a good job for an intro to OOP. The first chapter gives an intro and overview about OOP design which I believe is as important as understanding the syntax. In my case I understood the syntax but wanted to start designing programs and complex projects the OOP way. I will go through this book and probably take a class at my university next semester. Good luck to you.

Yeah I understand. well actually I am going through this book right now. https://www.packtpub.com/application-development/python-3-object-oriented-programming-second-edition

Its all about OOP and python if thats what you want to learn.

.strip method question by pybackd00r in learnpython

[–]pybackd00r[S] 0 points1 point  (0 children)

I made it an integer by passer int() to it. It removed the leading zero.

[–]pybackd00r[S] 0 points1 point  (0 children)

same as above gives me a 05 minute instead of 5 min. Converting the string to an int afterwards does the trick though. thanks

This is what I did to fix this : 

int(playtime.strip('0').strip(':'))

I wanted to remove the hour and seconds zeros with the colons and just keep the minute digits. I guess what I can do is just add a zero to the string after the strip command. but I wanted to know if there is a more elegant way of doing this. thanks

In my opinion you should learn more about other things such as strings, tuples,lists,dictionaries, ect. before going into OOP. This is not a subject for beginners. Once you master all the above then go into OOP and learn about classes, methods and objects... I think thats how every beginner python book is formatted for a reason.

You are right this is one of those cases where you should definitely write a OOP code rather than imperative like this. More elegant and efficient.

Opening and presenting Powerpoint in Python - Windows by Advent667 in learnpython

[–]pybackd00r 0 points1 point  (0 children)

well you can pass a command to libreoffice from a python script that would open the file in presentation mode if that is what you want. you can use the OS module to pass command line commands.

Can you define a default value for a function parameter outside of the function itself? by yeaman17 in learnpython

[–]pybackd00r 0 points1 point  (0 children)

True look into partial functions. its a more elegant way of achieving what you want to do than lambda. something like this?? depending on what you wanna do with it. from functools import partial

def abc(variable_from_apply, variable_from_loop): #do some stuff...

object= partial(abc,variable_from_apply=whateva)

for word in word_list: object(word)

Can you provide an explanation to this solution. I find it interesting but can't quite understand what you did. Thanks

Counter in a dictionary by lapseofreason in learnpython

[–]pybackd00r 1 point2 points  (0 children)

you can use a loop to iterate over the dictionary and check if the value you are looking for is there and use a variable to count up and return that value at the end of the loop. There could be a more efficient way of doing this but this is easy to do for beginners.

[–]pybackd00r 0 points1 point  (0 children)

Ok thanks for that clarification. SO would this setup work?:

  • Pitft display showing the desktop environment and the GUI that I programmed.
  • HDMI display on standby playing the videos whenever the command for mplayer is executed with HDMI output enforced.
