我正在使用套接字編程來發送 UDP 文本消息，并且工作正常。這是代碼：發送：import socketUDP_IP = "10.0.0.2"UDP_PORT = 5005MESSAGE = "Hello"print "UDP target IP:", UDP_IPprint "UDP target port:", UDP_PORTprint "message:", MESSAGEsock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDPsock.sendto(MESSAGE, (UDP_IP, UDP_PORT))接收：import socketUDP_IP = "10.0.0.2"UDP_PORT = 5005sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDPsock.bind((UDP_IP, UDP_PORT))while True:  data, addr = sock.recvfrom(1024)  print "received message:", data現在我想更改我發送到列表的消息。我試圖通過使用來做到這一點pickle。這是代碼：發送：import socketimport pickleUDP_IP = "10.0.0.2"UDP_PORT = 5005a = []a.append('H')a.append('G')MESSAGE = pickle.dumps(a)print "UDP target IP:", UDP_IPprint "UDP target port:", UDP_PORTprint "message:", MESSAGEsock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDPsock.sendto(MESSAGE, (UDP_IP, UDP_PORT))接收：import socketimport pickleUDP_IP = "10.0.0.2"UDP_PORT = 5005sock = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) # UDPsock.bind((UDP_IP, UDP_PORT))while True:  data, addr = sock.recvfrom(1024)  print "received message:", data  pickle.loads(data)  print(data)但是我沒有在接收方得到正確的列表形式。這是輸出：(1p0S'H'p1aS'G'p2a.(1p0S'H'p1aS'G'p2a.怎么了？
