Hello, I am trying to make a small game where the user has to guess what the area of the shape is and if they get it right then they get 2 points however, I am using an external file to store the score of the game in but every time I play through the game by entering my name, password I will see that the value of the score will be changed to 2 after I get the answer right but then when it calls the menu function the score in the file is reset and I don't know why

CORRECT ANSWER TO SAVE PRESSING BUTTONS IS B THE ONLY OPTION AVAILABLE TO PLAY IS TRIANGLE FOR NOW. If anyone could please figure this out it would be greatly appreciated.

Answer 1

This is because Python automatically overrides data in a file every time it is being opened. You are opening the file multiple times by calling the function multiple times.
