Question

For getting all the defined class attributes I try to go with

TheClass.__dict__

but that also gives me the special attributes. Is there a way to get only the self-defined attributes or do I have to “clean” the dict myself?

Answer 1

Another solution:

class _BaseA(object):
    _intern = object.__dict__.keys()

class A(_BaseA):
    myattribute = 1

print filter(lambda x: x not in A._intern+['__module__'], A.__dict__.keys())

I don’t think this is terribly robust and there might still be a better way.

This does adress some of the basic issues some of the other answers pointed at:

• No need for 'name convention' based-filtering
• Providing your own implementation of magic methods, e.g. __len__ is no problem (define in A).
