Learn coding??

So, I've had this dream for quite some time to make an RPG game and i take huge inspiration from Undertale, but the issue is that I do not know how to code ( I only have little knowledge of the basics in Python, and I've also coded many things in Scratch, but game development goes far beyond that). So, I decided to start learning coding via an app (the app in question is Mimo) and I'm doing well, though I'd like to ask for advice on how and where i can practice and learn more, specifically on developing games for free. Thank you!
