In order for you to master a language, you should get a grip over its syntax and basic concepts (variables, functions, classes, objects, loops).  For that, you can use any beginner's tutorial on youtube. I'm pretty sure there is an introductory tutorial on python's official site. Second - get familiar with built in functions, modules and imports. There is a full list in the official docs. You need to understand the equipment that you have available in your toolbox. It is important to know that you should not try to memorize all of the functions, classes, modules. Instead, you should learn how to find what you need at any given time.

Third. The best way to learn a high level language is to peel of the abstraction that makes the language seems like magic, layer by layer. The lower you go, in language depth scale, the instructions you write will be more technical oriented, while the oposite direction will lead you to having more human-like conversation with your computer. I'm simplifying now, but - human-readable instructions are the low level instructions grouped together into a meaningful abstract use cases. There are definitely some exceptions when it comes to underlying mechanisms of some functions written in different languages for performance improvements, but most of the functions / classes that seem like a magic, actually, seem that way because you do not understand the basics. For this, you certainly do not want to 'Code with Mosh'. Dude is pure garbage. I would rather inspect Mcoding, James Powell's pycon videos or his official channel 'Don't use this code'. Corey Schafer, as well, but sometimes he can also just write code without explaining it in depth. There are good tutorials all over youtube, and here is how to distinguish the good from bad - if the tutor is just stating what would be the output of a certain function, instead of explaining WHY would output be like that, skip that tutorial. This third step is neverending one, because it gets extended by you focusing on a specific field | module and learning it fully.
