Or even more precisely:
get_key_object_that_was_used_when_the_initial_value_belonging_to_that_key_was_inserted_into_dictionary
since rebinding other values to the stored key won't change it:
class Str(str):
def __repr__(self):
return str(self)+': '+self.tag
>>> a = Str('foo')
>>> a.tag = "I'm the first one!"
>>> b = Str('foo')
>>> b.tag = "I'm not."
>>> d = {}
>>> d[a] = 'bar'
>>> d[b] = 'spam'
>>> d.items()[0]
(foo: I'm the first one!, 'spam')
