Need advice on learnig python and data structures

I've been studying python for a while now and I've made 1-2 simple projects and I want to take my coding skills to the next level. I know basics python concepts (functions, classes, variables, loops, lists, dictionaries, etc). I also know most of the important functions of lists and dictionaries. My problem is that I don't know where to start or how to study data structures. I don't know how stack overflow works properly or how to code in data structures. I can do basic things like adding, removing or displaying elements. I know that for my problem I need to learn data structures so I want to know how to learn it with python. I would love if you know any resources or websites that I can study from, I don't mind if they are long tutorials, I just want to get better. I would also love a bunch of examples of problems to solve (including how to submit them on leetcode). I am also unsure if I should learn other python concepts before learning data structures or not. Thank you very much for your time and help, have a nice day.
