New submission from João Bernardo <[email protected]>:
I'm having trouble subclassing the int type and I think this behavior is a
bug... (Python 3.2)
>>> class One(int):
def __init__(self):
super().__init__(1)
>>> one = One()
>>> one + 2
2
>>> one == 0
True
I know `int` objects are immutable but my `One` class should be mutable... and
why it doesn't raise an error?
That gives the same result on Python 2.7 using super properly.
Also, if that's not a bug, how it should be done to achieve "one + 2 == 3"
without creating another attribute.
Things I also tried:
self.real = 1 #readonly attribute error
int.__init__(self, 1) #same behavior
I Couldn't find any related issues... sorry if it's repeated.
