Minecraft command generation

This is a proposition on using Python to dynamically generate commands, which is useful for things like function trees, repetitive code, and/or any large-scale projects.

Preface

Most of the code blocks presented are just snippets that don't do anything useful on their own. The idea is that the commented line is the command you'd expect to see by printing the object that follows.

Here's a classic example:

# say hi
commands.say(message='hi')
