在python34中：


    import socket, sys
    s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
    MAX = 65535
    PORT = 1060
    if sys.argv[1:] == ['server']:
        s.bind(('127.0.0.1', PORT))
        print('Listening at', s.getsockname())
        while True:
            data, address = s.recvfrom(MAX)
            print('The client at',address, 'says',repr(data))
            s.sendto('Your data was %d bytes' % len(data),address)
    elif sys.argv[1:] == ['client']:
        print('Address before sending:',s.getsockname())
        s.sendto('This is my message',('127.0.0.1', PORT))
        print('Address after sending',s.getsockname())
        data, address = s.recvfrom(MAX)
        print('The server', address, 'says', repr(data))
    else:
        print('usage: udp_local.py server|client')


python udp.py server  运行无误：

Listening at ('127.0.0.1', 1060)   

python udp.py client  出现问题：

Traceback (most recent call last):  
  File "d://udp.py", line 15, in <module>  
    print('Address before sending:', s.getsockname())
