After listening to the instructor's AWS lecture, I immediately paid for Python. I believed that I would do well, but it was an excellent class that exceeded my expectations. It is a systematic lecture. The best part is that it thoroughly organizes the concepts, and there are examples and homework!!! Even though I studied the concepts, I was confused a lot when I actually tried it, but I learned it by looking at the examples. Python beginners must take this lecture. Highly recommended!!!!!
