I have recently encountered an issue whenever I try and use pygame. The window that comes up hangs and just ends up crashing. I know this program works because I have run it many times before (this also occurs with anything else I try and run in pygame). Strangely, in the command prompt window it asks an input question from a completely unrelated program I was working on last night.
It could be, that you named your file pygame.py, so now, whenever you try to import pygame, it imports from THAT pygame.py file. Maybe delete/rename the file and reinstall pygame would work, i had the same problem a year ago and it worked.
