i am trying to make a simple adventure game with gemini ai and everything works fine except when i try to enter something in my tk.entry input box after starting the program. I can’t edit it when i click on it and for some reason this immediately gets fixed when i open another program and open my program again. Does anyone have an idea why this could be? I’m not experienced with python so i may have some beginner mistakes.

Take this simple code:

Recently as a task for school we’ve been making a basic program with a GUI and classes but me and my classmates have run into an issue where if a zero is at the front of the entry it often breaks. Everything works perfectly fine other than this one scenario (to see an example run it and type “0111” into the student/senior entry and press total cost) and I was wondering what the reason for this is, any ideas?

in my Code I have three Entrys, every time I click a button all the text in these Entrys disapears (as wanted). But now my cursor is stuck in the Entry and I can’t deselect it (not even manually).

I am having trouble setting a default value for a text entry widget in a Python 3.9 tkinter application.
I am using a StringVar as the text variable, and changing it using .set().
