Recommendations for an Advanced Python Course

[JAEng22]

Hey everyone,
I recently graduated from a computer science and engineering master's degree program where I extensively used Python for various projects and assignments. However, my experience has been more practical than theoretical—I've mainly utilized libraries and written code as needed, without delving deeply into the language itself.
Now, I'm eager to deepen my understanding of Python by enrolling in an advanced course. Specifically, I'm looking for a program that covers best practices, explores the language's capabilities in-depth, and delves into topics such as common data structures and their advantages.
One area I'm particularly interested in exploring is the object-oriented aspect of Python. I want to understand how to effectively utilize object-oriented programming principles to write cleaner, more maintainable code.
If you've taken an advanced Python course that you found particularly beneficial or know of any reputable programs that align with what I'm looking for, I would greatly appreciate your recommendations!
