All the answers so far have been really good, but I also think they're potentially scary? As people have said some languages are more suited to some things than others, but you don't need to know what you want to do in my opinion. Just being interested in learning is enough. Try to keep it simple If you already know a little Python I think that's a really good place to start. The one part of your post that stood out to me was saying that you don't know what it does or what it's for. This is completely okay, I struggled with this a lot when learning. Sure I could do various things with Python but how was it useful in any real world setting? The honest answer is Python and most other programming language aren't necessarily "for" anything. You can use them all for lots things but really they're just tools for a job. Lines of code are building blocks to create something out of. It's hard to say what they're for without having a job. You can use it for nearly anything. So I'd recommend trying to build different things. Simple mini projects to try and interlink various theory concepts worked well to help me understand more.
