Minimal syslog server in Python (working with 2.7 and 3.x)

syslog.py

#!/usr/bin/env python
try:
    import socketserver

class UDPHandler(socketserver.BaseRequestHandler):   
    def handle(self):
        print(self.request[0])

if __name__ == "__main__": 

    if len(sys.argv) == 3:
        port = int(sys.argv[2])
        address = sys.argv[1] 
        server = LoggedUDPServer((address, port), UDPHandler)
        print("Syslog server listening on UDP %s:%d\n\n" % (address, port))
        server.serve_forever()
    else:

        print("%s 192.168.10.33 514" % sys.argv[0])
        sys.exit(-1)
