Specifications • When the program starts, it should read the contacts from a CSV file named contacts.csv. Your instructor should provide this file if you don't already have it. • If the program can't find the CSV file, it should display an appropriate message and create a new CSV file that doesn't contain any contact data. • For the view and del commands, display an appropriate error message if the user enters an invalid integer or an invalid contact number. When you add or delete a contact, the change should be saved to the CSV file immediately. That way.
