Exiting only Pygame window

Im running a Pygame window using a GUI. When for example, a user clicks on a button on the GUI, the Pygame window appears. However, when I want to quit the Pygame window, my GUI quits too. Im sure this is beacuse of the following lines of code:

for event in pygame.event.get():
            if event.type==pygame.QUIT:
                pygame.quit()
                sys.exit()

sys.exit() exits everything, which is why the IDE closes with the Pygame window. But how do I only close the Pygae Window? Ive tried this:

for event in pygame.event.get():
            if event.type==pygame.QUIT:
                pygame.quit()
                break

But this doesnt work. Any suggestions?

The GUI im using Pyqt4 with Python 3.

I guess that your code snippet

for event in pygame.event.get():
    if event.type==pygame.QUIT:
        pygame.quit()
        break

is part of your main loop, running in an while loop, like

while True:
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            pygame.quit()
            break

The problem is that break will exit the for loop, not the while loop, eventually leading to an exception since you exit pygame but are probably trying to draw an the screen etc. etc.

A simple fix is to use a variable as condition for your while loop, like

quit = False
while not quit:
    for event in pygame.event.get():
        if event.type==pygame.QUIT:
            quit = True
        ...

or make sure to exit the while loop

while True:
    if pygame.event.get(pygame.QUIT): # only check for QUIT event
        break
    for event in pygame.event.get():
        ...
