A pure Python Levenshtein implementation that's not freaking GPL'd.
Project description
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.
Requirements
Python 2.7.X, Python 3.3+ or PyPy 1.6.0+
Usage
Usage is fairly straightforward:
import pylev
distance = pylev.levenshtein('kitten', 'sitting')
assert distance == 3License
New BSD.
Tests
Setup:
$ git clone https://github.com/toastdriven/pylev.git $ cd pylev
Running:
$ python -m unittest tests
Version History
v1.4.0
Updated for current versions of Python
Integrated a better Travis matrix. Thanks to @grainert!
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.
