# a route where we will display a welcome message via an HTML template "/") def hello(): In this file, we create a Flask route where we will display a welcome message using a Flask template. In this new directory, create a new file which creates the Flask application and runs it. Now we'll create a basic Flask app that serves a landing page on which we will display the classic text, "Hello World". To do this, install Flask using the command: $ pip install flask If you prefer virtualenv instead, be sure to check out the documentation, but just make sure you have a Python 3 environment active.īefore we can start serving static files with Flask, we need to install it and get a simple app going. Follow this guide to set up Python 3 using pyenv. You can use pyenv for this, which helps you select Python versions.
Here we will show you how to serve static files such as JS, CSS, and images using Flask. This approach has a huge advantage in keeping your code and workflow simple, particularly on smaller projects. This means it includes only what is necessary to do core web development, leaving the bulk of choices beyond that minimal subset to you. Unlike Django and other analogues like Ruby on Rails, Flask is a micro-framework. Flask is a great choice for building web applications in a modular way using Python.
