This project implements a CountdownTimer class in Python OOP, allowing users to start a countdown from a specified number of seconds.

Description

The CountdownTimer class is designed to provide a simple and intuitive way to create countdown timers in Python. It includes the following features:

Initialization: The CountdownTimer class is initialized with a specified number of seconds for the countdown.

Start Countdown: Use the start_countdown method to begin the countdown timer.

User Input Handling: The get_user_input function ensures that the user provides a valid integer input for the countdown timer.

Getting Started
