I cannot help with gdb, but I can point out that you have two
separate variables here. Decrement ing the local has no effect on
the global value.
The preferred way is to return any values from the function that
you want to use after it exits.
def next(i):
time.sleep(10)
i = 1 - i
return i
i = 1
while True:
i =next(i)
Another possibility, generally a bad idea, is declaring i global
in the function.
