Is there a 'multimap' implementation in Python?

Question

I am new to Python, and I am familiar with implementations of Multimaps in other languages. Does Python have such a data structure built-in, or available in a commonly-used

Answer 1

There is no multi-map in the Python standard libs currently.

WebOb has a MultiDict class used to represent HTML form values, and it is used by a few Python Web frameworks, so the implementation is battle tested.

Werkzeug also has a MultiDict class, and for the same reason.
