A simpler solution is mentioned in the comments on the page.
#! pip install string-grouper
import pandas as pd
from string_grouper import match_strings
df = pd.read_csv (“corporate_list.csv”, encoding = “ISO-8859-1”, header = None)
df.columns = [“serial”, “company_name”]
ndf = match_strings (df[“company_name”])
ndf[ndf[“left_index”] ! = ndf[“right_index”]].to_csv (“to_study.csv”)
