.... won't work. In this case mod would always be "foo".
You have to inspect the stack in order to get the module of the
caller. The implementation of warnings.warn() gives you some examples
how to get the module name.

Thanks for the quick and very helpful reply. Basically just copying from
warnings.warn(), I came up with this:
import sys
class A(object):
def __init__(self, mod=None):
if mod is None:
self.mod = sys._getframe(1).f_globals['__name__']
else:
self.mod = mod
In warnings.warn() they used try around sys._getframe(1). As far as I
understand what is done in warnings, there it is not sure what object
caused the warning and therefore it is not sure whether you can or
cannot use sys._getframe(1). Though in my case it should be quite clear.
Can I be sure that my code will always work?
