For example, use getaddrinfo () to get a method that Baidu.com provides HTTP services

I have been engaged in pythonWeb development for a year. Now I am confused. I mainly work on curd, that is, how to obtain data, and then present it to the front-end page. The framework uses django, optimization means adding memecache. Pay attention to this when querying the database. Currently, there are a lot of tangled issues: 1: the programming of process threads, how to use it in practice 2: network
