I would like to recommend this to those who are familiar with Python grammar and have some experience using Python. I only roughly understood the asynchronous method with my eyes, but I have never properly understood it and used it. It was refreshing and fun to actually implement some actions using the asynchronous method. The lecture did not just teach the core parts, but it was good that it explained the necessary contents first before explaining the core contents of the lecture in a way that felt like a beginning, development, turn, and conclusion(?). (Before explaining concurrency and parallelism, it explained basic concepts such as CPU, process, and thread.) Although this seems basic, there are many lectures that do not follow it well. If you upload lectures on Python or Python frameworks in the future, I would like to listen to them all. Thank you for the great lecture.
