[visionegg] Re: Terminating a While Loop

How about something as simple as:

quit_now = False
pause = False
while not quit_now:
        if not pause :
                p.go()
        for event in pygame.event.get():
                if event.type == pygame.locals.KEYDOWN :
                        if event.key == pygame.locals.K_ESCAPE :
                                quit_now = True
                        if event.key == pygame.locals.K_SPACE :
                                pause = not pause
You could also set quit_now to True to quit if you reach some criterion level from your experiment.

Hello,
Im currently working on the following code trying to determine a way to exit a while loop before the criteria is satisfied. 

i=0
        while i<eval(self.number.get()):
                p.go
                i=i+1
My goal is to set it to a certain key that will either pause the program, and then resume it once pressed again, or have it exit the program all-together, either/or would be acceptable.
I had tried setting it to the "esc" key by doing the following code that I found while searching for an answer: 
      if msvcrt.kbhit() and msvcrt.getch() == chr(27):
           break
But that just causes the program to fail to start up.
I have also tried:
for event in pygame.event.get():
        if event.type == pygame.locals.KEYDOWN:
            if event.key == pygame.locals.K_ESCAPE:
                  sys.exit()
But this again just causes the program to fail to start up.

Any suggestions would be greatly appreciated.
