Question

In python, If I have a class foo, I can call foo.__module__ to get a string with the name of the module it is part of.

If I have a module bar, I can call bar.__file__ to get a string with the path where the module was loaded from.

How, when I only have class foo can I get the path of the module it is part of? (foo.__module__ returns a string, not an instance of the module it names)

Answer 1

sys.modules is a mapping from module name to module:

sys.modules[foo.__module__].__file__
