Is there a way to set the default_factory of defaultdict so that accesses to undefined keys get to set to the key?
i.e. if d['xxx'] were accessed and there was no key 'xxx' then d['xxx'] would get set to 'xxx' I know I can define a function with lambda for the default_factory, but I don't see how to access the key. I tried: d = defaultdict(lambda: key) But that did not work. -- https://mail.python.org/mailman/listinfo/python-list
