python- the udp socket programming

Use udp protocol

Server:

Import socket
 # 1 Creating an object tpye = SOCK_DGRAM udp udp protocol on behalf of 
SK = socket.socket (of the type = socket.SOCK_DGRAM) 

# 2 binding Ip and port (register the host in the network, so that other servers can be found in the host)

# . 3 transmits and receives data logical
