The Levenshtein distance or edit distance between two strings is given by the minimum number of operations needed to transform one string into the other, where an operation is an insertion, deletion, or substitution
[What is Levenshtein Distance? "In information theory, linguistics and computer science, the Levenshtein distance is a string metric for measuring the difference between two sequences. Informally, the Levenshtein distance between two words is the minimum number of single-character edits (insertions, deletions or substitutions) required to change one word into the other. It is named after the Soviet mathematician Vladimir Levenshtein, who considered this distance in 1965.[1]
Levenshtein distance may also be referred to as edit distance, although that term may also denote a larger family of distance metrics.[2]:32 It is closely related to pairwise string alignments."](https://en.wikipedia.org/wiki/Levenshtein_distance)
The Levenshtein distance algorithm has been used in:
Spell checking Speech recognition DNA analysis Plagiarism detection
This simple and fast module provides the capability to easily compare two strings. Returned is a number between 0 and 1 that represents exactly how much the strings appeared alike/different.
