There may be clearer and more succinct ways of writing it, but they
all do roughly this:

def whocalled():
    import sys
    try:
        raise ""
    except:
        return sys.exc_traceback.tb_frame.f_back.f_back.f_code.co_name

def test():
    def f():
        return whocalled()
    def g():
        def h():
            return whocalled()
        return h()
    print f(), "was the caller"
    print g(), "was the caller this time"

so in a function whocalled() returns the name of the function that
called the function calling whocalled(). Confused? Good.
