Comprehensions in Python the Jedi way

by Bjørn Friese

Beautiful is better than ugly. Explicit is better than implicit.

-- The Zen of Python

I frequently deal with collections of things in the programs I write. Collections of droids, jedis, planets, lightsabers, starfighters, etc. When programming in Python, these collections of things are usually represented as lists, sets and dictionaries. Oftentimes, what I want to do with collections is to transform them in various ways. Comprehensions is a powerful syntax for doing just that. I use them extensively, and it's one of the things that keep me coming back to Python. Let me show you a few examples of the incredible usefulness of comprehensions.

-c, --cookie-jar <file name> File to save response cookies to.

How to setup an OpenShift registry

• Create registry with oadm

oadm registry --latest-images --create \
              --credentials=/var/lib/openshift/openshift.local.config/master/openshift-registry.kubeconfig

• Create route (optional, alternatively you can use also the internal ip of the registry service later)
