Pygame exiting after certain time

Question

I have a pygame code which I wanted to be executed for only X seconds, I tried

sleep(10)
pygame.quit()

It just continues to run.

Answer 1

Change

sleep(10)
pygame.quit()

to

from sys import exit
sleep(10)
pygame.quit()
exit()

Answer 2

Though the program could exit a few milliseconds off your actual time, you could try to use the method defined in this answer and constantly check by resetting time.time() repeatedly in a while loop which should be fairly easy since you are using PyGame after all:

import time
start_time = time.time()

while True:
    if time.time() - start_time() >= 10:
        pygame.quit()
