本文详细介绍了Python标准库中的socket模块，包括低级网络接口、地址解析、常量和函数等。涵盖了各种地址类型如AF_UNIX、AF_INET、AF_INET6，以及不同地址家族、套接字类型和相关错误处理。此外，还提到了socket对象的方法，如accept、bind、connect等，以及网络相关的常量，如SO_*、MSG_*等。

  >> AF_INET
     a pair (host, port)
     >> host
        domain | ip
     >> port
        integer number
  >> AF_INET6
     a four-tuple (host, port, flowinfo, scopeid)
     >> flowinfo
