I think the biggest strength of this class is that you practice by typing commands directly. Of course, you can't understand and acquire everything through one practice, but the teacher records the class lectures and uploads them, and captures the coding screen while the class is in progress, so it's useful for review. Also, it was good that he shared useful materials in the middle of the class, as well as episodes and implications that he had while analyzing data. Also, the teacher's lecture tone and speed were good, so it was easy to understand the lecture content. He also kindly responds to questions right away. I recommend this to those who are new to Python like me and want to learn how to process real data and the overall process.
