You chose Python !
It's really nice for back-end programming, but if you want front-end (design and such, interactions with users of your website) it's not the best to begin with (as it's much more difficult than JavaScript for this matter), but for back-end (server-side, scraping, calculations, databases, data manipulation, and a lot more) it's the one I prefer (I code in Python 50% of my time I think, it's got my favors).
But as it seems it's to develop finance applications, you made the right choice, Python is the best (with C++) for that.
Good luck on your journey ! Welcome to the wonderful world of coding, life will never be the same !
