My project needs to import the crawled Coursera data into the database for future work, such as PHPNow that the data has been crawled, the format exists in the folder, the picture belongs to a directory, I am a data rookie, do not know how to design a database to the correct existence of the data in MySQL? (using navicat), I hope you master Liberal enlighten, younger brother grateful! Reply content: My project needs to import the crawled

I have climbed the URL of all the courses on Coursera and placed it in the All_url.txt file, about 2000 lines. Then I want to use these URLs to crawl other information I want, to synthesize a. csv to facilitate the import of the database. In the following code, I've only written a few things I want to crawl to test for implementation (such as the crawl of the course schedule, and so on, five of the information I need is not written in the code), but a

I posted my microblog two days ago, but Wu lide from Fudan Institute of Computer Science is running? The elements of statistical learning )? This course is still in Zhangjiang... how can I miss Daniel's class? I'm sure I have to ask for leave to join the class... in order to reduce the psychological pressure, I also pulled a bunch of colleagues to listen to it. A dozen of eBay's mighty people killed the past! We always feel that we have more than Fudan students, and the classrooms of 50 or 60 pe
