Both HTML and Python are useful skills to have, but they serve different purposes. If you're interested in creating websites and web pages, HTML is a good place to start. It's a markup language that's used to structure the content of a website. On the other hand, if you're interested in general-purpose programming, Python is a good language to start with. It's a widely used, high-level programming language that's known for its simplicity and readability.
So, it depends on your end goal, if you want to create a website, HTML is a good starting point, if you want to do a wide range of programming tasks, Python will be a good starting point. But you can always learn both and also in parallel.
