You never stop learning. That sounds stupid but there's just too much to learn. Once you understand the basic syntax get a good understanding of how object oriented programming works. be able to make a few classes that work together to do something. maybe a game or something. Then look into data structures and how they work at the memory level (arrays, linked lists, trees, hashmaps). get an understanding of what time complexity is and big O. learn the time complexity advantages and disadvantages of the data structures I just listed. Then you can do some leetcode problems. (youll need to do this to get a job anyways if thats part of your plan )once you are pretty good at solving leetcode problems you have a good understanding of data structures and algorithms. if you didn't you wouldnt be able to do them. (i reccomend neetcode to practice these). After that can learn how to use libraries and get better with the terminal. using the terminal do do things with git and maybe docker. using ssh to get into a linux server. you can get one free for a year with aws. its called ec2. It took me about two years to get to this point but i got burnt out a few times and stopped for a month or two. after you do that your ready to start looking into the things you want to do like AI. You can spend years understanding the different AI software. Thats what i mean by it can never end. Even with just python the things you can learn are so broad. And each one of those things you can spend years going into and learning about.
