While trying to wrap arbitrary objects, I came across a problem with dictionaries and lists. Investigating, I managed to come up with a simple piece of code whose behaviour I simply do not understand. I hope some of you can tell me what is going on:
>>> class Cl(object): # simple class that prints (and suppresses) each attribute lookup
... def __getattribute__(self, name):
... print 'Access:', name
...
>>> i = Cl() # instance of class
>>> i.test # test that __getattribute__ override works
Access: test
>>> i.__getitem__ # test that it works for special functions, too
Access: __getitem__
>>> i['foo'] # but why doesn't this work?
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'Cl' object has no attribute '__getitem__'
