I am actually interested in the answer to this question for Python
versions 2.4, 2.6 and 3.x.

__file__ is optional. If set, this attribute’s value must be a string.
The import system may opt to leave __file__

I see I wrote the below a little too quickly! Don't forget to take
the reciprocal when printing. You might want to modify my naming of

Use case: I want to allow a user of my Solitaire Scorekeeper program

This is a plain text only list that does not (typically) allow file
attachments. So I do not see any code. So if you wish for

I thought that this might be of interest to the group for those who do
not follow the Tkinter mailing list as I have seen questions here
about how to do Python GUIs in Android where the usual response is to
try Kivy. Perhaps there is now a tkinter solution?

I have stumbled upon some articles by Leonardo Giordani that deal with
OOP in Python. He has two sets of articles. The one concerning
Python 2 is located at:

The one concerning Python 3 is at:

I am trying to understand the functionality that the Python module,
curses, provides. But I am stuck on how to use the command,
curses.resizeterm(nlines, ncols). At
https://docs.python.org/3/library/curses.html#curses.resizeterm it says:

Under https://docs.python.org/3/library/curses.html#window-objects in
the curses docs, it states:
window.addch(ch[, attr])
window.addch(y, x, ch[, attr])
[...]
Note
Writing outside the window, subwindow, or pad raises a curses.error.
Attempting to write to the lower right corner of a window, su
