The input JSON for test is kinda in in DynamoDB dump format:

A Beginner's Hip Hop Playlist

Edit: After some constructive feedback on hacker news, I think that it's worth mentioning that this playlist is very skewed towards recent material, although I've included some essentials from the past.

I think that hip hop is one of the most, if not the most, misunderstood genres of music. In this playlist, rather than focusing on one artist or one type of hip hop, I tried to give examples of a bunch of different artists with songs ranging from the early 90's all the way up until 2017. The songs are in no particular order and the sounds cover a very broad spectrum. Some of them are pretty damn explicit, so I wouldn't necessarily throw this playlist on if there are kids around. I provided the lyrics to each song, the sub-genre that I'd put the artist in (very rough), and a brief description. This playlist is not by any means meant to be comprehensive and in many cases doesn't necessarily represent the artist's "best" song, but instead aims at exposing you to some of my fa

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.
