Fuzzy and FuzzyWuzzy: what are the differences in text comparison?
In the source code you can find a simple explanation of what does partial ratio in fuzzywuzzy does:

Return the ratio of the most similar substring
as a number between 0 and 100

In this code snippet you can find the differences
from fuzzywuzzy import fuzz

fuzz.ratio(&quot;this is a test&quot;, &quot;this is a test!&quot;)
Out:    97

fuzz.partial_ratio(&quot;this is a test&quot;, &quot;this is a test!&quot;)
Out:    100
