You have been warned... $ cat pp.py i = 42 ++i print i --i $ pychecker pp.py Processing pp... 42 Warnings... pp.py:2: Operator (++) doesn't exist, statement has no effect pp.py:4: Operator (--) doesn't exist, statement has no effect ...or you would have been, had you used the pychecker :-) Now I'm not recommending >>> class Int(object): ... def __init__(self, value=0): ... self.value = 0 ... self.half = False ... def __pos__(self): ... if self.half: ... self.value += 1 ... self.half = not self.half ... return self ... def __str__(self): ... return str(self.value) ... __repr__ = __str__ ... >>> i = Int() >>> i 0 >>> ++i 1 >>> ++i 2 >>> i 2 which is slightly harder to fix than to break but gives some (weak) motivation not to rule out multiple prefixed signs.
