I’ve recently picked up Dataquest again and am as impressed with their content as I was when I first encountered it. I started by reviewing the basic data cleaning mission.
At the end of the mission a few additional tasks and questions are suggested to continue practicing. I picked up the challenge and did them after redoing to cleaning examples in the courseware from memory on my own system (by downloading the dataset as opposed to simply coding in their online environment).
The practice was a great way to consolidate the lessons of the course, mainly related to munging with Pandas.
Another result of this exercise was to drive home that I should probably get around to migrating this blog to Pelican so I can just use notebooks to create posts.
You can see my notebook here.
