Build a Python Flask URL Shortener

# Introduction

In this project, we will learn how to create a URL shortener using Python and Flask. A URL shortener is a tool that takes a long URL and converts it into a shorter, more manageable URL. This can be useful for sharing links on social media or in emails, as well as making long URLs more user-friendly.
