Purpose

An opinionated setup for python on Mac OSX. Opinions subject to change as new tooling gains traction. I've used this setup for the past ~5 years.

Prerequisites

Understanding of a .bashrc or .zshrc file. Why? There are commands that need to be ran every time you open a terminal window. If you don't have a strong opinion about your own "rc" setup file, install ohmyzsh. This will give you some sane defaults for your terminal, makes it clear where to do things like modify your $PATH env var (needed for a good python or node setup), and adds some nice extras like displaying the version of node you are currently using. The tldr; for installing ohmyzsh is below, but you'll want to read through the docs to understand how to utilize it...

sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Transforming Code into Beautiful, Idiomatic Python

Notes from Raymond Hettinger's talk at pycon US 2013 video, slides and pycon US 2015 video

The code examples and direct quotes are all from Raymond's talk. I've reproduced them here for my own edification and the hopes that others will find them as handy as I have!
