python-Levenshtein is Levenshtein Python extension and C library.

Because the project home page has been defunct since January 2008, I put a copy of the code into my own repository: mirror of python-Levenshtein

From its README:

The Levenshtein Python C extension module contains functions for fast computation of

• Levenshtein (edit) distance, and edit operations
• string similarity
• approximate median strings, and generally string averaging
• string sequence and set similarity

It supports both normal and Unicode strings.
