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, 3)

License

New BSD.

Tests

Setup:

$ git clone https://github.com/toastdriven/pylev.git
$ cd pylev

Running:

$ python -m unittest tests

Version History

  • 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.
