this code that i wrote runs fine in my ide and the exe version. but the problem arises when i try to close the program. it shows me this error(and yes, i've imported sys and used sys.exit() instead of quit().):

File "source.py", line 77, in 
File "source.py", line 41, in main
for event in pygame.event.get():
NameError: name 'quit' is not defined

my game is almost done, and this is the only thing that bothers me. any help would be appreciated.
You need to write pygame.QUIT instead of quit
exe version of code shows error message when i try to close it
