In fact, I am a new software student who jsut finished his python class. I am learning myself how to work with pygame. In fact, I am trying to implement a math game which proposes random math equations to solve and wait the users input before moving to the next equation. In my case, each time I write my answer (it appears in the next iteration of the while loop with another math equation (not the original question). I partly understand why this is happening but I am not really able to solve the problem
Here is my code for the moment, some elements are still missing though
