如何实例（x，模块）？

Question

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

I need this for initializing some dispatcher function and I want that the function can accept either dict or module as an argument.

Answer 1

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

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

Answer 2

我喜欢使用它，所以你不必导入类型模块：

isinstance(amodule, __builtins__.__class__)
