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.
