Hello,

I've been trying to match records from two different CSV files and deleting the ones which do not match.

Here's the exact question:

The Membership.csv file contains details of people who are no longer members.
The Attendances.csv file is the up-to-date list.
The manager wants you to find out which members should no longer be included in the
membership list.

How can I solve this problem? Please help

Thanks
