Project page: http://ceptord.net/20181215-polyleven.html
Install
$ pip install polyleven
Usage
Polyleven provides a single interface function "levenshtein()". You can use this function to measure the similarity of two strings.
>>> from polyleven import levenshtein
>>> levenshtein('aaa', 'ccc')
3
If you only care about distances under a certain threshold, you can pass the max threshold to the third argument.
>>> levenshtein('acc', 'ccc', 1)
1
>>> levenshtein('aaa', 'ccc', 1)
2
In general, you can gain a noticeable speed boost with threshold k < 3.
