how to talk to __main__?

[Michal Wallace]

Hey all,

I understand why __name__ evaluates to "__main__",
but how come you can't say __main__.x = 1 to reassign
some global variable x?

I realize this is sort of bad practice to start out with... But,
for example... with my callback I wanted to do:

##########
allDone = 0

def callback():
    allDone = 1  # allDone is local, so this won't work
    #__main__.allDone = 1 # gives an error

# assign callback() to external event here...

while not allDone:
    pass

print "All done!"
