A pure Python Levenshtein implementation that's not freaking GPL'd.
Based off the Wikipedia code samples at http://en.wikipedia.org/wiki/Levenshtein_distance.
- Python 2.7.X, Python 3.3+ or PyPy 1.6.0+
Usage is fairly straightforward:
import pylev
distance = pylev.levenshtein('kitten', 'sitting')
assert distance == 3New BSD.
Setup:
$ git clone https://github.com/toastdriven/pylev.git $ cd pylev
Running:
$ python -m unittest tests

v1.5.0
- Added an alternatives section. Thanks to @graingert for the start!
v1.4.0
- Updated for current versions of Python
- Integrated a better Travis matrix. Thanks to @graingert!
- Fixed mistaken docs about the assert. Thanks to @adamchainz!
- Reorganized the package.
- Blacked all the source code.
v1.3.0
- Implemented a considerably faster variants (orders of magnitude).
- Tested & working on Python 2.7.4, Python 3.3.1 & PyPy 1.9.0.
v1.2.0
- Fixed all incorrect spellings of "Levenshtein" (there's no "c" in it).
- Old methods are aliased for backward-compatibility.
v1.1.0
- Implemented a much faster variant (several orders of magnitude).
- The older variant was renamed to
classic_levenschtein. - Tested & working on Python 3.3 & PyPy 1.6.0 as well.
v1.0.2
- Python packaging is REALLY hard. Including the README this time.
v1.0.1
- Python packaging is hard. Including the README this time.
v1.0.0
- Initial release, just the naive implementation of Levenshtein.
