Video Demo: https://youtu.be/LMo8FGahBnI

Description:

The Phone Book Management System is a simple Python-based application for managing contact information. This project allows users to add new contacts, search for contacts by phone number, and store contact details in a JSON file. The contact details include the following fields:

• First Name
• Last Name
• Phone Number
• Age
• Country

Features

• Add Contact: Users can add a new contact with the necessary details.
• Find Contact: Users can search for a contact by their phone number and view their details.
• JSON Storage: Contacts are stored in a JSON file for persistent storage.

Project Structure

• project.py: Contains the main logic for managing contacts, including adding and finding contacts.
• test_project.py: Contains test cases for the functions in project.py using the pytest framework.
• requirements.txt: Lists the required packages, including pytest for running tests.

How to Run

1. Install the required packages:

   pip install -r requirements.txt
   
   

2. Run the application:

   python project.py
   
   

3. Run the tests:

   pytest test_project.py
   

Example Usage

Upon running the program, users will be presented with a menu to add a contact, find a contact by phone number, or exit the application:

```sh
  1. Add contact
  2. Find contact by phone number
  3. Exit

To add a contact, users need to follow the prompts to enter the contact's first name, last name, phone number, age, and country. The information will be stored, and a confirmation message will be displayed. To find a contact, users need to enter the phone number, and if the contact exists, their details will be displayed in a readable format:

```sh
  Contact found:
  Name: John Doe
  Last Name: Doe
  Phone: 1234567890
  Age: 30
  Country: USA

If the contact is not found, an appropriate message will be displayed.
