Python Console App Development

I have an existing Python script that needs to be ported to a console app.

Key Requirements:
- Porting of the existing Python script to a user-friendly console app in Python 3.x
- Implementation of input/output handling to ensure the app is interactive and easy to use

Ideally, the developer should have:
- Proficiency in Python programming and understanding of Python 3.x features
- Experience with developing console apps
- Strong skills in implementing user-friendly interfaces
- A good understanding of input/output handling in Python

As the original script has already been developed, the focus here is on the user interface and experience. If you have a good understanding of Python, experience in building user-friendly console applications, and a passion for creating clean, efficient code, I'd love to hear from you.
