Python UDP Server Client

Python is a simple udp server and Client example. The server needs to be started first and then the client starts.

#-*-Coding: cp936 udp Server first-*-zdt

Import socket, time
Import random
L Port = 8013
Rport = 8012
Host = "localhost"
S = socket. socket (socket. AF_INET, socket. SOCK_DGRAM)
# Receive UDP datagram from any sender from a given port
S. bind (host, Lport ))

Print 'Bind to the ', host, Lport
While True:
Try:
Data, addr = s. recvfrom (1024)
# Receive a datagram (up to 1024 bytes)
Print 'stored ed: ', data, "from", addr
S. sendto (data, (host, Rport ))
If data = 'exit ':
Break
Except t:
Print "error in client ..."
Break

S. close
Msg = raw_input ("Press any key to exit ...")

Import socket, time, random

# Time. sleep (1)
