I took the advice of a fellow forum member and converted an Othello game I had written for my mother to run in wxPython instead of tkinter. I'd had absolutely no experience with wx when I started doing this and I'm very happy that the tkinter bug that plagued the help section of my previous attempt in tkinter is non-existent. Everything, with the exception of the single player mode, that I want in the app has been successfully implemented but there are just a few more tweaks I would like to make and the app occasionally freezes when certain menu items are clicked. Specifically, my goals are:
1) Make the grid of buttons that serves as the gameboard look more like an Othello gameboard; it'd be nice if it looked more like the original (see attached screenshot)
2) Find a fix for the occasional freezing the app experiences from time to time. It seems to happen mostly when selecting certain menu items and buttons.
3) Add a single player mode. I'm not sure whether I'd need to do this with neural networks, or if that'd be overkill and there's an easier way to do it.
4) Increase the size of the help dialog. It's way too small for my liking. I tried using a SetSize method which wx.Dialog inherits from wx.TopLevelWindow, I believe. It had no effect.
I've included some screenshots along with my code.
Edit: I've updated my source code. I've written thorough internal documentation complete with docstrings, the error message that flashes on a gameboard button now specifically describes the reason why the attempted move is invalid, and the app now asks the user whether they want to save if they close the app on an open game.

# The wxPython implementation of an Othello game I wrote for my mother.
# These are displayed in help windows when an item from the help menu is selected:
gameRules = """Game Rules
Othello is a game played on a board with an 8x8 grid on it. There are 2 players and 64 gamepieces, enough to fill the entire gameboard. Each piece has a black side and a white side and each player plays as either black or white. The goal is when either the board is filled or their is no valid move available to either player for the majority of the pieces on the board to have your color upturned.
The application will automatically assess whether an attempted move is valid but to alleviate the frustration of guessing where one can place a gamepiece, here is a brief explanation:
If a space is already occupied, the move is invalid.
If there are no adjacent pieces, the move is invalid.
When there are adjacent pieces, their must be at least one vertical, horizontal or diagonal row of your opponents pieces with another of your pieces on the other end.
When you place a gamepiece, all adjacent vertical, horizontal or diagonal rows of your opponents pieces with another of your pieces at the other end will be flipped.
You may occaisionally find yourself in a situation in which there is no valid move available to you but your opponent has a valid move. You can give your opponent your move by clicking their player button. The text in their button will turn red, indicating that it is their turn. If there are no valid moves available to you, it will say so in the status bar.
"""
applicationHelp = """Application Help
Options Menu:
The options menu provides options for starting a new game,
saving a game, opening an existing game, saving and quitting and
quit without saving. A single player gamemode is also listed in
this menu, but it is not yet implemented.
Give Move to Opponent:
There are situations in which the current player has no valid
move, but their opponent does. In this situation, you give your
move to your opponent by clicking their player button (one of the
large buttons at the top or bottom of the window.) The text in
their button will turn red indicating that it's their move.
Options Menu Items:
New Game -- Start a new game.
New Single Player Game -- coming soon
Save Game -- Displays a file navigator to locate and select a save
file to save the current game. The destination file must be a
text file (*.txt). The application will remember the path of a
current saved game until it is closed, so you won't be prompted
for a save file if you have specified one already. When 'new
game' is clicked, the path of any previously specified save file is
forgotten to avoid overwriting a pre-existing saved game.
Save Game As -- Allows you to save a previously saved game
under a different name. This feature can be used for among
other things, creating back-ups of your saves.
Open Game -- Displays a file navigator to locate the a save file
(*.txt) to open a pre-existing game. The filepath of the
selected game is remembered until the application is closed,
so you won't be prompted to re-select the file when saving.
Save and Quit -- Automatically saves the game before exiting. If
no file has been previously specified, the user will be prompted
for a save file.
Quit Without Saving -- Quits the game without saving.
