If x is an instance of a class, then sys.modules[x.__class__.__module__]
will give you the module that the class was defined in; from there,
__file__ gives you the file name (but not the line number, as far as I
know).

If f is a function, then f.func_code has attributes co_filename and
co_firstlinenumber.

I don't think there's anything you can find out about the source
of any other kind of object.
