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.

Work in progress, I'll write this up properly when I'm done.

Almost all credit goes to @maxogden for putting me on to this and pointing me in the right direction for each of these items.

Prerequisites:

• Raspberry Pi
• Kindle Paperwhite freed from its locked down state (jailbroken) http://www.mobileread.com/forums/showthread.php?t=198446
  • You have to downgrade your Kindle to 5.3.1 to install the current jailbreak; that's just a matter of getting the old version image, putting it on your Kindle via USB and telling it to install "upgrade". Then you put in the Jailbreak files, load the ebook and break.
• Your kindle will be quick to detect an upgrade is available so it'll want to upgrade soon afterwards but the jailbreak will last but you have to reinstall the developer certificates so it's a bit of a pain but doable. Find all the instructions on the mobileread.com forums and wiki.
