Yes, I have. I've been teaching myself Python off and on for the past 2 years, but really ramped up with it last year and created an app that uses the DocX API to create invoices through Terminal. I've also been building a suite of Casino games since I couldn't find any good accessible versions of them around, along with some fun little math apps for quick flash card problem training.
Here are links to my invoice app and games on github. I updated them to Python 3 and they are playable through Terminal, iTerm, power shell, or whatever other command line apps that can run Python:
$1 - Robust and fully featured Craps game.
$1 - An accessible Baccarat game that I just finished.
$1 - My first game, a robust Blackjack game.
$1 - Creates invoices through the command line and saves out a nicely designed Word document
As I have more time, I'm looking into programming a bot for Kik, web scraping apps for keeping track of grocery and product sales, and any other task that I need and can be automated.
