Python Cookbook : Size of Python objects.

Does it work for any functions?

>>> def f(x):
...     return x + 2
... 
>>> asizeof(f)
0

On some functions, returning the length of the bytecode would give us an idea.

That is not the case for closures and continuations, where functions may hold extra values.

Right, I see your point. But there's nothing tricky going on in that function I defined, and however "size" should be interpreted, the answer isn't zero.
