Fuzzysearch is a Python module that implements fuzzy (or approximate) matches of subsequences in data. It can find parts of a sequence that match a supplied subsequence with up to a maximum Levenshtein distance. Can also do fuzzy insertions, deletions, and substitutions. Appears remarkably simple to use for such a powerful feature. The advanced demonstration involves analyzing a DNA sequence, to give you an idea of how sophisticated a capability this is. Installable with Pip. Python v2.x and v3.x compatible.
