Rust implementation of levenshtein distance (https://en.wikipedia.org/wiki/Levenshtein_distance), based on Wagner–Fischer_algorithm (https://en.wikipedia.org/wiki/Wagner%E2%80%93Fischer_algorithm).
pip install fastlevenshtein
First param is either a list or a str.
It will be compared to the second param that is a str.
The third param is the maximum value of levensthein. For example, if the third param is 3, if the levensthein value reach at least 3, the function with exit and return 3 as value. This third param is used to increase computation time when you are only interested in string that are close to each other. If you do not want to use early exit, you can just use a really high value for this param
from fastlevenshtein import levenshtein levenshtein("string1", "string2", 999) # 999 so no early exit >>> 1 from fastlevenshtein import levenshtein_list levenshtein_list(["string1", "string2"], "string3", 999) >>> [1, 1] from fastlevenshtein import levenshtein_list levenshtein_list(["aaaaaaaa", "bbbbbbbb"], "ccccccc", 3) # early exit at 3 maximum value for levensthein distance >>> [3, 3]
