Hello to whoever this may concern, After downloading Python 3.8.5 IDLE, an error message popped up, saying the code execution cannot proceed because python38.dll was not found. What should I do in order to use the Python interpreter? Thank you!

Re: Issue with Python module downloads from Library for a beginner Python coder.
by Sarvesh Poddar Aug. 2, 2020

Aug. 2, 2020

Hi, I am currently using Python 3.8.5 with IDLE environment that comes pre-installed with the Python application. I am using the book "An Introduction to computer science" by John Zelle as my reference. The problem I am facing is "There is a python program named "graphics.py" that is used as reference in the book and I downloaded the python file from internet (link to the file - https://mcsp.wartburg.edu/zelle/python/graphics.py). I have kept this module in (C:\Users\sarvesh\AppData\Local\Programs\Python\Python38-32) and this is were my Python files also lie in C drive. The problem is that I am not able to import graphics.py file and when I try to do that following is the error I receive, Traceback (most recent call last): File "<pyshell#0>", line 1, in <module> import graphics File "C:\Users\sarvesh\AppData\Local\Programs\Python\Python38-32\graphics.py", line 1 Python 3.8.5 (tags/v3.8.5:580fbb0, Jul 20 2020, 15:43:08) [MSC v.1926 32 bit (Intel)] on win32 ^SyntaxError: invalid syntax I have installed, uninstalled and then re-installed Python 3.8.5 multiple times but the problem remains. I did a thorough internet search and most of them suggested using sys path and following is the result, import sys>>> sys.path['', 'C:\\Users\\sarvesh\\AppData\\Local\\Programs\\Python\\Python38-32\\Lib\\idlelib', 'C:\\Users\\sarvesh\\AppData\\Local\\Programs\\Python\\Python38-32\\python38.zip', 'C:\\Users\\sarvesh\\AppData\\Local\\Programs\\Python\\Python38-32\\DLLs', 'C:\\Users\\sarvesh\\AppData\\Local\\Programs\\Python\\Python38-32\\lib', 'C:\\Users\\sarvesh\\AppData\\Local\\Programs\\Python\\Python38-32', 'C:\\Users\\sarvesh\\AppData\\Local\\Programs\\Python\\Python38-32\\lib\\site-packages'] When I write a different line - (from import graphics *), this is the output: from graphics import *Traceback (most recent call last): File "<pyshell#3>", line 1, in <module> from graphics import * File "C:\Users\sarvesh\AppData\Local\Programs\Python\Python38-32\graphics.py", line 1 Python 3.8.5 (tags/v3.8.5:580fbb0, Jul 20 2020, 15:43:08) [MSC v.1926 32 bit (Intel)] on win32 ^SyntaxError: invalid syntax Please do let me know if I am missing out something very basic.

You do not provide much detail to diagnose what your problem(s) is(are). By the "earlier one" is it the same version as the one you re-installed? Were you able to run IDLE with the "earlier one"? By not being able to import modules do you mean modules from Python's standard library? Or do you mean installing third party libraries using pip? > ...But now I am not able to open IDLE after multiple tries. Have you looked in your start menu in the list of installed programs for Python? If it is there did you expand it and see if there is an entry for IDLE? How have you been trying (unsuccessfully) to open IDLE? -- boB

questions re: calendar module
by o1bigtenor Aug. 2, 2020

Aug. 2, 2020

Greetings I regularly work in planning through multiple years at once. This means that I like to have a lot of stuff available in a calendar function. Python seems to be locked when I need to display more than 1 year at a time. I don't see a way to display something like 3 years worth of calendar starting at a point 23 months from now. (I see how to display 1 year at a time but not multiple years.) Is there a way to do this? TIA

Pygobject style question
by Chris Green Aug. 2, 2020

Aug. 2, 2020

Having (after lots of help from here, thank you) finally converted my Python 2, gtk 2 program to Python 3 and pygobject gtk 3 I'm left with a couple of what might be called style questions. I guess it's mostly down to what feels right to me but there may be good reasons for choosing one way over another and, if so, I'd like to know what they are. So, my original code had:- ... ... self.buffer = gtk.TextBuffer() self.view = gtk.TextView(self.buffer) ... ... This doesn't work in gtk+ 3 (or at least I don't think it does, the converter script changed it) and there seem to be several ways of doing it now:- ... ... self.buffer = Gtk.TextBuffer() self.view = Gtk.TextView(buffer = self.buffer) ... ... ... ... self.buffer = Gtk.TextBuffer() self.view = Gtk.TextView.new_with_buffer(self.buffer) ... ... ... ... self.view = Gtk.TextView() self.buffer = self.view.get_buffer() ... ... ... ... self.view = Gtk.TextView() self.buffer = Gtk.TextBuffer() self.view.set_buffer(self.buffer) ... ... Is there any reason to prefer any one of the above over the others? Obviously the last one is a line more but lends itself to using several Gtk.TextBuffer objects in on Gtk.TextView. -- Chris Green ·

Non IDE development strategy - what do others do that's fairly simple?
by Chris Green Aug. 2, 2020

Aug. 2, 2020

I have a few python programs that I have written which I need to do some fairly extensive changes to (to get from gtk to gobject and to move to Python 3). This is on a Linux (xubuntu 20.04) system. I use the command line to do just about everything (even though the program is GUI!) and so I tend to edit in one window and test in an adjacent window on the same screen, I don't find GUI development environments comfortable. The existing code simply lives in ~/bin with a couple of modules in ~/bin/pymods (which directory is in my PYTHONPATH). I use mercurial for configuration management of the code, directly in the ~/bin directory. This works fine for the sort of minor bug fixing and updates that I do most of the time, I'm the only user so changing the 'live' code isn't a major issue and I can always drop back to the last working version using mercurial. However with this more major change to do I really need a 'development' copy of the code as well as the live working copy as it's likely I will take a few days to do the changes (as in an hour or so each day over some days) and I need the ability to use the program meanwhile. So, finally to the question, does anyone else have this command line based sort of approach and, if so, what do they do to provide a 'development version' of a program in parallel with a working version? I guess virtualenv (Python 2) and venv (Python 3) address this problem but they do feel rather more complex than I actually need and I'm not very clear how you move code from the virtual environment to 'live'. There's also the issue that I'm moving code from Python 2 to Python 3 so which virtual environment should I use? Any ideas or suggestions would be very welcome. -- Chris Green ·
