Add Contact
Part of the Logic & Flow section of Coddy's Python journey — lesson 18 of 78.
Challenge
EasyNow, create the add_contact function that takes one argument: contact_book (a dictionary). The function should:
- Get input for the contact's name, phone, email, and address.
- Check if the name already exists in the dictionary. If it does, print:
"Contact already exists!". If not, save the contact in the following format:
contact_book[name] = { "phone": phone, "email": email, "address": address }Then print:
"Contact added successfully!".
