process.extract*: Inconsistent behaviour between python2 and python3 when using pandas.Series

[normanius]

When executing the following code, process.extract* functions do not behave consistently.

from fuzzywuzzy import process
import pandas as pd

a = pd.Series.from_array(['abc', 'def', 'ghi'])
process.extractOne('abd', a)

In python2 (python 2.7.12, pandas 0.20.3, fuzzywuzzy 0.15.1) the output is:

('abc', 67,)

In python3 (python 3.5.2, pandas 0.20.3, fuzzywuzzy 0.15.1) the output is:

('abc', 67, 0)

So apparently (following the documentation in process.p), fuzzywuzzy under python3 interprets pd.Series as a dictionary and not as a list-like object.

Not entirely sure if the problem is on the fuzzy side - but some users might get confused when migrating from python2 to python3.

We're unlikely to fix this as all of our applications are python2. That said, I'd be happy to review a pull request that fixes the issue :)

The inconsistency indeed originates from pandas (pandas-dev/pandas#13918) and will be solved for future versions (pandas>=0.21).

No further action required, I guess. Sorry for bothering you. :)

No worries, thanks for digging!
