Daniel Arbuckle's Mastering Python

Installing Flask

Flask is laser-focused on making it easy to write handlers for HTTP requests and doesn't really do anything else. That makes it very well-suited for writing a microservice that processes a few specific requests while using minimal resources.

Flask isn't part of a Python standard library, but it's easily installed using pip, as shown in the following command line:

$python3 -m pip install flask

As always, you can add --user to the command to install Flask into your personal Python package library, or you can install it into a virtual environment if you prefer.
