Simple Web App with Flask and Heroku - Python GUI for Beginners 

In this tutorial, I will show you how to create a Web Application with Flask!
This video the also the first episode of The Battle of the App Frameworks, where 🤩🤩 YOU GET TO CHOOSE THE WINNER! 🤩🤩
Today we will create a simple "Hello World" Application with Flask, which includes:
* an HTML template containing the structure of a web page
* a CSS stylesheet containing design instructions
* a Python backend that communicates with a web server
And we will also 🚀DEPLOY🚀 this application for free with Heroku! 😁
This tutorial covers all the basics of Flask, from start to finish! (excluding Javascript interactions, which we will leave for later 😜)
