I couldn’t tell what you were doing. This is how I would do it.
from fuzzywuzzy import fuzz
from fuzzywuzzy import process
Create a series of tuples to compare:
compare = pd.MultiIndex.from_product([df1['Company'],
df2['FDA Company']]).to_series()
Create a special function to calculate fuzzy metrics and return a series.
def metrics(tup):
return pd.Series([fuzz.ratio(*tup),
fuzz.token_sort_ratio(*tup)],
['ratio', 'token'])
Apply metrics
to the compare
series
compare.apply(metrics)
There are bunch of ways to do this next part:
Get closest matches to each row of df1
compare.apply(metrics).unstack().idxmax().unstack(0)
Get closest matches to each row of df2
compare.apply(metrics).unstack(0).idxmax().unstack(0)
