Best way to learn

Hi guys

So i'm jumping into python, but I'm being overwhelmed with all the information out there.

I'm an MSc student studying Chemistry, and specialising in Computational Chemistry, where python is really handy for data analysis, as well as full on AI.

But I want to eventually work in programming, or at least make money on the side from programming, so I will want to learn multiple languages eventually.

But back to python, my biggest problem to start with is all the ways to learn. My plan is to go from knowing nothing, to mastering it, so to speak. But I don't find continuous videos. By that I mean, I find a "Python for beginners" which is 4 hours long, great. But then the same guy doesn't do the next step, so when I find other videos, half of the video might be going over the stuff you already learnt?

So what would you guys say is the best way to learn python to an advanced level
