This article is a python tool that crawls Reader magazines and uses reportlab to generate pdf files after learning beautifulsoup. I will also share it with you, for more information, see. After learning beautifulsoup, I made a web crawler, crawled Reader magazines, and produced them as pdf using reportlab ..
