Hi,
The following code worked on Python 3.2, but no longer works in 3.4. Did
something change, or have I always been doing something dumb?
(I realise the code is pointless as is - it's the simplest example I can give
of a problem I am seeing with more complex code).
>>> class Foo:
... def __new__(cls, *args, **kargs):
... print('new', args, kargs)
... super().__new__(cls, *args, **kargs)
...
>>> class Bar(Foo):
... def __init__(self, a):
... print('init', a)
...
>>> Bar(1)
new (1,) {}
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "<stdin>", line 4, in __new__
TypeError: object() takes no parameters
What I was expecting to happen (and what happens in 3.2) is that the
object.__new__ method passes the argument to the __init__ of the subclass.
Any help appreciated.
Thanks,
Andrew
