Binary package “python-levenshtein” in ubuntu xenial

extension for computing string similarities and edit distances

 The Levenshtein module computes Levenshtein distances, similarity ratios,
 generalized medians and set medians of Unicode or non-Unicode strings.
 Because it's implemented in C, it's much faster than the corresponding
 Python library functions and methods.
 The Levenshtein distance is the minimum number of single-character
 insertions, deletions, and substitutions to transform one string into
 It is useful for spell checking, or fuzzy matching of gettext messages.
