Question

def a():
    print __name__

Is there any chance I can have such a function, but have it print the “correct” module name if imported by another module and called from there?

“Correct” module name should always be the one it is called from.

Answer 1

The sys module provides a CPython specific way to lookup your caller:

sys._getframe(1).f_globals.get('__name__', '__main__')

The _getframe() function is documented here, and frame objects are documented here.
