I came to take this course because I was curious about how design patterns are implemented in Python, as I transitioned from developing only with Java and Spring to developing with Python and FastAPI. The explanations of the design patterns themselves and how to implement them in Python were very good, but when explaining the lecture, you tell us to look at the code on the screen, yet the code isn't displayed on the screen, so it's necessary to view it together with the lecture materials. The lecture proceeds in a format of scrolling through the lecture materials, and due to this lecture style and the method of having to alternate between the materials mentioned above, if you miss something in the middle, you find yourself constantly searching through the lecture materials to find where the explanation is. The lecture content is so good, but the lecture structure and materials are disappointing.
