I first encountered Python crawling on YouTube and it was very helpful, but I haven't done it for a long time so I don't remember it well, so I bought the course. As expected, it was explained well from a beginner's perspective, and although it was the same method, it was slightly different, and it was repeated through examples (from various sites) so that I could master it repeatedly, which was very helpful. In addition to crawling, if there are other courses related to Python, I will buy them. Thank you.
