  Methods Description socket.socket() Used tocreate sockets (required on both server as well as client ends to create sockets) socket.accept() Used to accept a connection. It returns a pair of values (conn, address) socket.bind() Used to bind to the address that is specified as a parameter socket.close() Used to bind to the address that is specified as a parameter socket.connect() Used to mark the socket as closed socket.listen() Used to connect to a remote address specified as the parameter Important methods of the socket module www.edureka.co/python
