Answer to Question #198514 in Python for Andu

Question

Project 1: Phonebook

Implement a program that manages a smartphone phonebook. Each contact might have the following data: name, surname, birthday and a set of Phone Numbers (to the same contact we may assign several phone numbers). The data are stored into a json file. The application should manage the following characteristics: create and add new contact the book ,remove existing contact (contacts are identified by name) , show all the contact , show the list of persons among your contact the has the birthdate

Changes need to be stored back in the file. The above functionalities are implemented through methods of a class named PhoneBook. The application interacts with the user through a menu where the user is asked for the next action to undertake (e.g., 1-Add new contact, 2- Remove Existing contact, etc.) Put comments in your code
