I'm trying the below code, but it's just returning the matching ratio

compare = pd.MultiIndex.from_product([data['Content'],
                                      data['Content1']]).to_series()

def metrics(tup):
    return pd.Series([fuzz.ratio(*tup),
                      fuzz.token_sort_ratio(*tup)],
                     ['ratio', 'token'])

compare = compare.apply(metrics)
