How is isinstance (x, module)?

Question

I need to check if a variable is a module or not. How to do it in the cleanest way?

I need this to initialize some dispatcher function and I want the function to be able to accept either a dict or a module as an argument.

I like to use this, so you don't need to import the types module:

isinstance(amodule, __builtins__.__class__)

>>> import os, types
>>> isinstance(os, types.ModuleType)
True

(It also works for your own Python modules as well as built-in ones like os

.)
