I'm coding a game using wxpython with multiple *.py scripts and I would like to, when I press a button from the main script, another script is launched. 
Example: I launch a *.py script for the game menu window that has multiple options. When I press the options button, it will launch an other script that was assigned to that button an open the options window
How can I do that? Thx
have you tried using subprocess?
you can assign button event to subprocess to launch another py script.
Open a py file from pressing a button on another py file
