Any of the courses from the University of Helsinki [1]. They are free for everyone, have good explanations, and most importantly, great exercises to practice programming with an auto-grading system that gives feedback when you make mistakes.

Programming is really only something you learn when you have to do it. Most of the online courses online (DataCamp being one of them) have very simple assignments that can be done via copy/paste, so people at least feel like they learned something and stay engaged. That's simply not good enough. You need complex assignments that really make you struggle a bit, so you engage with the material on a deeper level.
