Jellyfish >= 0.7 only supports Python 3, if you need Python 2 please use 0.6.x.

Included Algorithms

String comparison:

  • Levenshtein Distance
  • Damerau-Levenshtein Distance
  • Jaro Distance
  • Jaro-Winkler Distance
  • Match Rating Approach Comparison
  • Hamming Distance

Phonetic encoding:

  • American Soundex
  • Metaphone
  • NYSIIS (New York State Identification and Intelligence System)
  • Match Rating Codex

Example Usage

>>> import jellyfish
>>> jellyfish.levenshtein_distance(u'jellyfish', u'smellyfish')
>>> jellyfish.jaro_distance(u'jellyfish', u'smellyfish')
>>> jellyfish.damerau_levenshtein_distance(u'jellyfish', u'jellyfihs')
>>> jellyfish.metaphone(u'Jellyfish')
>>> jellyfish.soundex(u'Jellyfish')
>>> jellyfish.nysiis(u'Jellyfish')
>>> jellyfish.match_rating_codex(u'Jellyfish')

Running Tests

If you are interested in contributing to Jellyfish, you may want to run tests locally. Jellyfish uses tox to run tests, which you can setup and run as follows:

pip install tox
# cd jellyfish/
