🚀 Python Using UV + Flask + Docker

Welcome to the Python Using UV learning project! This simple yet powerful setup is aimed at exploring UV, the blazing-fast Python package manager, and running a basic Flask app using Docker and docker-compose. Video refrence : https://www.youtube.com/watch?v=6pttmsBSi8M

📚 About the Project

This project demonstrates how to:

• Replace pip, virtualenv, and requirements.txt with UV.
• Use UV to manage packages and environments.
• Run a simple Flask app via uv run.
• Containerize the project with Docker and manage it via docker-compose.
