Answer to Question #198527 in Python for Andu

Question

Project 5: Social Media account

Implement a program that manages the data of the social media account. The user can access only his/her own account. The account is characterized by username, password, name, sumame, birth date and list of friends (characterised by the account username). The data are stored into a json file. The application should manage the following characteristics:

Sign up: register to the system

Sign in: by providing usename and password and showing all the user data

Search for a user (using name and surname)

Add a used to the friend list

Changes need to be stored back in the file. The above functionalities are implemented through methods of a class named SocialMedia. The application interacts with the user through a menu where the user is asked for the next action to undertake (e.g., 1-Sign Up, 2

Sign In, etc.) Put comments in your code.
