First, the class method of the socket module:
Socket.socket (Family,type)--Creates and returns a new socket object
SOCKET.GETFQDN (name)-Converts an IP address string with a well-segmented location into a full domain name
Socket.gethostbyname (name)--resolves the hostname to an IP address string separated by a dot number
SOCKET.FROMFD (Fd,family,type)--Create a socket object from an existing file descriptor
Second, the Socket module instance method:
Sock.bind ((Adrs,port))--binds the socket to an address and port
Sock.accept ()--Returns a client socket (with client-side address information)
Sock.listen--Set the socket as a listening mode to monitor the backlog of incoming link requests
Sock.connect ((Adrs,port))--Connect the socket to the defined host and port
SOCK.RECV (Buflen[,flags])--accepts data from a socket up to Buflen characters
Sock.send (Data[,flags])--send data via socket
Sock.close ()--close socket
Sock.getsockopt (lvl,optname)--Gets the value of the specified socket option
Sock.setsockopt (Lvl,optname)--Set the value of the socket option
