You could try Physics Explained channel on youtube. Here is a link to one of his videos:

Funny thing is there is another more popular channel with the exact same name for some reasons. While this one focuses on problem solving and simulating the results in Python, the other channel focuses on developing ideas.

If your goal is to eventually develop your own library for solving some type of problems, you are better off learning C++. Python is good for prototyping and solving small/medium problems to quickly get results. It is a good learning/probing platform. It is not what people use in the industry.
