You will implement the edit_contact function. In the function, do the following:
-
- Ask the user to enter the name of the contact they want to edit.
- If the contact exists, in a loop, give them the following choices
- Remove one of the phone numbers from that Contact.
- Add a phone number to that Contact.
- Change that Contact's email address.
- Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!)
- Stop editing the Contact
- Once the user is finished making changes to the Contact, the function should return.
