One of the projects that I like to work on in my spare time is turning games into text-based Python scripts that can be played from the terminal. Some of the games that I have done include Jeopardy, Wheel of Fortune, and, most recently, Hangman. These started out as a way to practice the things I was learning in my Python courses but quickly turned into a hobby as I found that I enjoyed the challenge. While these do not necessarily apply to my data science aspirations, the practice and thinking process that I have learned in making these has been invaluable in its applications to my coursework and other projects.
As an example of the games I have been writing, below is an embedded console that runs the Hangman program using Trinket.
