Long ago, the first time I read "The Pragmatic Programmer", I read some advice that really stuck with me.
"Don't Use Manual Procedures".
This in the chapter on Ubiquitous Automation. To summarize, they want you to automate all the things.
The trouble was that I hadn't much of an idea how to actually go

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