apandasexfuzz 0.13

Intuitive way of using fuzz matching in pandas
Updates
05.10.2022 - Added compare rows
Installation
#Try it first like this:
#rapidfuzz is a lot faster than fuzzywuzzy, but I had some problems installing it, #even with Visual C++ 2019 redistributable installed a-pandas-ex-fuzz will try to import this module first
pip install a-pandas-ex-plode-tool
pip install a-pandas-ex-df-to-string
pip install rapidfuzz #https://github.com/maxbachmann/RapidFuzz
pip install --no-deps a-pandas-ex-fuzz

#if rapidfuzz does not work, use:
pip install a-pandas-ex-plode-tool
pip install a-pandas-ex-df-to-string
pip install fuzzywuzzy
pip install --no-deps a-pandas-ex-fuzz

#Or if you want to try to install everything:
pip install a-pandas-ex-fuzz

Compare values in column against each other: pandas.Series.s_fuzz_all_values_in_col()
from a_pandas_ex_fuzz import pd_add_fuzzy_matching
pd_add_fuzzy_matching() #adds three new methods to pd.
import pandas as pd

df = pd.read_csv(
"https://raw.githubusercontent.com/pandas-dev/pandas/main/doc/data/titanic.csv"
)
df11 = df.Name.s_fuzz_all_values_in_column(
limit=5, merge_with_series=True, partial_full_weighted="weighted"
)
df22 = df.Name.s_fuzz_all_values_in_column(
limit=2, merge_with_series=False, partial_full_weighted="full"
)
df33 = df.Name.s_fuzz_all_values_in_column(
