Hi, I was getting some surprising false positives as a result of not expecting this:
all(element in item for item in iterable) to return True when 'iterable' is empty. I guess it goes into hairy Boolean territory trying to decide if an element is in an item that doesn't exist (if that's what's happening), but I would have thought not. It seems inconsistent with the behaviour of any(element in item for item in iterable) which returns False when 'iterable' is empty. Sorry if this has come up before, but 'any' and 'all' make for fruitless googling! Any light to be shed? Regards, John -- http://mail.python.org/mailman/listinfo/python-list
