How to share a variable between two Python classes?
I am not an experienced programmer so please keep that in mind. I have a made an application with Tkinter, it's called a dice rolling simulator. The code contains three classes:
- The login screen (class 1)
- The privacy terms (class 2) (subclass class 1)
- The game-screen (class 3)
So basically the players have to read the privacy terms and press the button ok, to acknowledge that they have read the privacy terms. I am trying to make a realistic game. They cannot play the game until they have read the privacy terms.
My question: How can iI pass a variable from class 2 to class 1? In
In class 1 i have declared a variable start_game = False and in class 2 if the user has read the terms than I change the variable to True.
How can I pass the adjusted variable back to class 1 so that the users can play start the game.
If they haven't read the terms and they try to start the game than a error message pops up.
I hope I have made it clear to you.
