Trouble with .after() Tkinter

[purpleicetwice]

This code will always ask the same question, i.e. the last question found, so it appears that it is not working because it puts up the same question. Add a print statement to the function to prove this to yourself.

 for question in questions: if question.difficulty == newDifficulty: newQuestion = question 

I got it to work omg!! I put a print statement after

screen1.after_cancel(after_id)

The timer was being cancelled as soon as the button was created. Now the .after_cancel() is at the start of nextQuestion. Thanks for the help :D
