Transforming Code into Beautiful, Idiomatic Python

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

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!

Looping over a range of numbers

for i in [0, 1, 2, 3, 4, 5]:

	on settings.py change the DATABASES config to something like this:

	DATABASES = {
	"default": {
	"ENGINE": "django.db.backends.postgresql_psycopg2",
	"NAME": "[YOUR_DATABASE_NAME]",
	"USER": "[YOUR_USER_NAME]",
	"PASSWORD": "",
	"HOST": "localhost",
	"PORT": "",

	# JSON Resume

	[JSON Resume] is an easy way to produce an adaptible and professional-looking resume. We recommend that you use it. It'll save you a lot of headaches about formatting, file types, and the like. Plus, it'll make you look like you know how to Internet.

	This is what the underlying format looks like:
	```
	{
	"basics": {
	"name": "John Doe",
	"label": "Programmer",
