I was listening to Kim Young-han's Java lecture and needed Python, so I paid for the lecture right away, but the level is so different that I can't help but think it's the worst. Instead of teaching the principles naturally, he just writes code in the same way as the rote learning he taught 5 years ago, and there are no example problems, so it's impossible to internalize. Even though I've been exposed to Python to some extent and know it a little, when I watch this lecture, I don't understand it clearly and have a lot of questions. I can't help but think that he hired comment workers to manipulate the lecture reviews.
