It's the best!!! After crawling while crying and eating mustard, the speed was too slow, so I was thinking of a solution and wanted to improve my understanding of Python, and then I happened to find Inflearn and this lecture. Although it's an appendix, it was a curriculum that I really needed because I could see AWS being used in practice. (I'm studying Python, backend, and AWS intensively.) You also explained the basic principles concisely, so I gained a lot of knowledge. I also purchased the lectures on classes and object orientation!! I will keep watching the lectures and diligently make them mine. Please continue to provide great content in the future!!
