I was at a loss when I was trying to move from C++ to Python, but my worries disappeared after purchasing this book. The lectures felt slow, so I recommend 1.5x speed. The book has detailed pictures and explanations, and covers a lot of parts that aren't in the videos, so I highly recommend the book. The author is active on GitHub, KakaoTalk group chats, and Discord, so he explains the book and coding-related questions well. The book is good, and the summary is also good. ㅎㅎ I recommend it to those who are moving to Python. Since the pictures and explanations are specific, I recommend the book in that language to those who are preparing in another language. The author has also uploaded other video lectures.
