I have learned R reading stack overflow and watching YouTube. Nowadays there is also AI, do not spend money on more courses, all the entry level information is for free online.

Kaggle has lots of courses for python, they are free.

Much better to start to work on projects though. Possibly something that is full stack, e.g. how to web scrape some data with python, store it in a mysql database, analyse it and then visualise it in an excel report or a dashboard in tableau. In a real job you will need to learn to use many pieces of software, you can’t learn all of them in advance. Learn how to learn while working on a project. No course is going to teach you that and this can be your advantage.
