Sorry to bother everyone again, but I have this problem bugging me:
#!/usr/bin/python -i
class Foo(object):
def nostat(self,val):
print val
nostat.__orig_get__ = nostat.__get__
@staticmethod
def nostatget(*args, **kwargs):
print 'args:', args, 'kwargs:', kwargs
nostat.__orig_get__(*args, **kwargs)
nostat.__get__ = nostatget
setattr(nostat,'__get__',nostatget)
f = Foo()
f.nostat('a')
print f.nostat.__get__ is f.nostat.__orig_get__
This produces:
a
False
I expected to see 'nostatget' output: nostat.__get__ = nostatget
obviously failed to replace this function's __get__ method.
I don't quite understand the above sentence, so I'm assuming that you
wanted the final "is" test to be "True" instead of "False".
It looks like you've replaced ...
(A) the original __get__() method
... with ...
(B) a new method that *calls* the original __get__() method
So why should you expect (A) and (B) to be the same object?
The question is why? Isn't __get__ a normal attribute of a function nostat?
This is made so much weirder that nostat.__get__ is no longer original
__get__, so it looks like it should have been replaced, but if so, why
nostatget doesn't get called?
