Not really. Both can have very different types and very different
interfaces. There are types, classes, functions, methods, objects with a
dedicated __call__() method, ... Any of them can be implemented in Python
or C (or other native languages, or a mix of more than one language).

What's your use case? There might be other ways to achieve what you want.
