Don't worry, this is all for the future. I'm still on python.
Well, I'm not sure I'd want to go into HTML5 for game dev without actually knowing HTML5 in the first place. I feel like I wouldn't learn as much, especially if I plan on using HTML5 for things other than games.
Still, it's a possibility, so thanks for the suggestion.
NINJA EDIT: If I don't try HTML5, I'll just use PyGame and see if I can get it working. I was playing around with Pyglet as well which could also work.
Sounds like you've been using Python for a while now, how about giving pygame a try?
You're ready for it!
