Appendix A: Installing Python on Windows, Mac, and Linux

A. Installing Python

Let's make sure that we have python 3 installed by running python --version in the terminal. If we get command not found or if the version is lower than 3.0.0, we'll need to upgrade first. We will want to use the virtualenv module to create isolated virtual enviornments so that we can isolate the libraries we install to just the project folder. The Flask Documentation provides installation instructions, but it is not quite as comprehensive.


The reccomended setup is to use VS Code with Windows Subsytem for Linux (Windows 10+). A full tutorial is provided by Microsoft here.
