How to check to which module a function belongs? Like,
check_module(sqrt)
Would return math
and so on, if at all.
Functions have a __module__
attribute:
>>> from math import sqrt
>>> sqrt.__module__
'math'
You can use the inspect.getmodule()
function to get the actual module object for a given object:
>>> from inspect import getmodule
>>> getmodule(sqrt)
<module 'math' from '/Users/mj/Development/Library/buildout.python/python-3.4/lib/python3.4/lib-dynload/math.so'>
inspect.getmodule()
works for more than just functions and classes; it'll go through some length to find a module for a given object, based on the metadata on that object.
