Out of curiosity, why do you want to do this? > 1.

It does do what you asked it to do. You asked class A to store the "foo" object under the name "bar". When you create an instance of B, and ask for the "bar" attribute, it isn't found in class B, so Python looks to the parent class. The parent class, A, does have an object named "bar", so Python returns that. And that object is the same object that you asked be named bar, namely the "foo" function. If you want "bar" to be a function that *calls* the "foo" function, declare it as such: py> class A(object): ... def foo(self): ... print 'foo' ... def bar(self): ... return self.foo() ... py> class B(A): ... def foo(self): ... print 'moo' ... py> B().bar() moo > 2. At least in 2.3 (and 2.4, AFAIK), you can't pickle classes that do > this. In Python 2.4: py> class A(object): ... def foo(self): ... print 'foo' ... bar = foo ... py> import pickle py> pickle.loads(pickle.dumps(A)).bar <unbound method A.foo> py> pickle.loads(pickle.dumps(A())).bar() foo Or maybe I misunderstand you?
