for humans:


For hack value, here is a possible implementation:


import inspect


def _find(frame, obj):
    for name, value in frame.f_locals.iteritems():
        if value is obj:
            return name
    for name, value in frame.f_globals.iteritems():
        if value is obj:
            return name
    raise KeyError("Object not found in frame globals or locals")


class X:
    def debug(self):
        print ("Caller stores me in %s (among other possible places)"
               % _find(inspect.currentframe(1), self))



>>> xyzzy = X()
>>> xyzzy.debug()


Caller stores me in xyzzy (among other possible places)

>>> a = b = X()
>>> a.debug()


Caller stores me in a (among other possible places)

>>> b.debug()


Caller stores me in a (among other possible places)

>>> X().debug()


Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "<stdin>", line 4, in debug
  File "<stdin>", line 8, in _find
KeyError: 'Object not found in frame globals or locals'
