Whatever you do, get good at using at least one editor. You'll use it a LOT in your development career.
Just one small clarification on Pygame. It's a framework that allows you to build stuff from the ground up. It doesn't have all the bells and whistles of a typical game engine like Unity or RPG Maker which allows you to drag and drop items into a world. You'll have to render every little detail explicitly, or use an existing framework or engine that someone else developed using the Pygame library. It's a great way to learn how to create games from scratch but won't allow you to create things out of the box. Judging from the OP's post I figure he/she knows that already but just thought I'd add that for future reference.
Sounds like you want to be a story writer. Why not just start writing stories on your own? I'm not in the industry but I assume story writers for games have English language backgrounds (or Spanish in your case) and have a portfolio of short stories that game development teams can look at when hiring a writer.
For an example check out 'Kingdoms of Amalur.' The famous sci-fi writer, R. A. Salvatore, created the lore for the game. The story is amazing. The lore was one of the things that made it a great game.
