In [47]: fuzzywuzzy.fuzz.partial_ratio("red", "random") Out[47]: 33 In [48]: fuzzywuzzy.fuzz.partial_ratio("rod", "random") Out[48]: 33 In [49]: fuzzywuzzy.fuzz.partial_ratio("prod", "random") Out[49]: 25 In [50]: fuzzywuzzy.fuzz.partial_ratio("pred", "random") Out[50]: 50
why "pred" is more similar to "random" than "prod"?

This is a known issue in python-Levenshtein: #79 In your case for the comparision of
"prod" <-> "random"
the following alignment is used:
"prod" <-> "ndom"
which has a similarity of 25. However the optimal alignment would be:
"prod" <-> "rand"
which has a similarity of 50. In FuzzyWuzzy you will get the correct result when the slower difflib based implementation is used:
>>> from fuzzywuzzy import fuzz >>> from difflib import SequenceMatcher >>> fuzz.SequenceMatcher = SequenceMatcher >>> fuzzywuzzy.fuzz.partial_ratio("prod", "random") 50
Sorry, something went wrong.
