Flask Tutorials

In this tutorial, you’ll build a small web application that renders HTML text on the browser. You’ll install Flask, write and run a Flask application, and run the application in development mode. You’ll use routing to display various web pages that serve different purposes in your web application.

Upon completion, you’ll be able to use this sequence of steps to jumpstart your next Flask app. In this step, you’ll add a few routes to your application to display different pages depending on the requested URL. With some minimal styling, your Flask web project is starting to look like a finished web app.
