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]:

Isolating development environments by using language tools

RVM for Pythonistas, Virtualenv for Rubyists

For Python Developers: virtualenv, virtualenvwrapper or Buildout

Note: envs = environments

This gist has been moved to its own Github repo, so it's easier to contribute with additions and corrections. Please open a PR there if you see any mistake, I don't track comments on here as there's no notification system for gists AFAIK. Thanks.

	It's not rare to mercurial 'push' commands return the annoying abort message:

	$ hg push --rev <WORK_BRANCH>
	pushing to <REPO URL>
	searching for changes
	abort: push creates new remote head <HEAD ID> on branch <WORK_BRANCH>!

	Usually this means that you didn't updated your local repository with other programmers code.
	The usual fix is to update your main branch by pulling changes, merge your local repository with remote changes,
	commit the merge and then push to the remote repo:
