failure.csv

In above two file msisdn available in failure.csv are also available in Success.csv so i have to delete entries for these msisdn from success.csv file in python. Please suggest.

Answer 1

I think that a good approach would be using pandas. You can load the files as pandas DataFrames and then do something like this:

import pandas as pd
source = pd.read_csv("./success.csv")
failure = pd.read_csv("./failure.csv")
success[~success.MSISDN.isin(failure.MSISDN)]

I hope this will help you.
