How do you use Ansible to automate the setup of a Python application?

Quick answer: an Ansible playbook for a Python app typically installs Python itself, sets up a virtual environment and package manager (pip or poetry), installs the app's dependencies, and configures a web server in front of it — the same repeatable steps every time, instead of manually SSHing in to set each server up by hand.

Ansible is another configuration management tool that lets us personalize the server, and for this our app is a Python app, so we're going to make sure we've got some Python installed — that'd be a great start, wouldn't it. It's then going to install a virtual environment and a package manager, pip or Poetry or something, that installs all the dependencies. It's going to install a web server, and once all that's done we can get our thing running — easy peasy.
