First python project
This document discusses getting started with a first Python project. It covers installing Python and choosing an IDE, following coding best practices like PEP8 style guidelines, using built-in data structures, testing tools, virtual environments, project structure, and deployment tools like Supervisor. The goal is to help new Python programmers understand the basics of starting their first project.

Editor's Notes
- #21 Vagrant, an open-source product released in 2010, is best described as a VM manager. It allows you to script and package the VM config and the provisioning setup. It is designed to run on top of almost any VM tool – VirtualBox, VMWare, AWS, etc.
