是否可以使用Python通过UDP套接字发送数组？我正在使用Python
2.5并尝试发送一个简单的数组，但是它不起作用。它可以成功发送数组，但是当我尝试将其与数组中的某个项目一起打印时，程序将崩溃。我不确定会发生什么错误，因为我采取了预防措施，将数据转换为数组，但无法正常工作。希望我尽可能清楚地解释这个问题。我将不胜感激！

# Client program

from socket import *
import numpy
from array import*

# Set the socket parameters
host = "localhost"
port = 21567
buf = 4096
addr = (host,port)

# Create socket
UDPSock = socket(AF_INET,SOCK_DGRAM)

def_msg = "===Enter message to send to server===";
print "\n",def_msg
a = array('i',[1,3,2])
# Send messages
while (1):
    data = raw_input('yes or now')
    if data!= "yes":
        break
    else:
        if(UDPSock.sendto(a,addr)):
            print "Sending message"

# Close socket
UDPSock.close()



# Server program

from socket import *

# Set the socket parameters
host = "localhost"
port = 21567
buf = 4096
addr = (host,port)

# Create socket and bind to address
UDPSock = socket(AF_INET,SOCK_DGRAM)
UDPSock.bind(addr)

# Receive messages
while 1:
    data,addr = UDPSock.recvfrom(buf)
    L = eval(data)
    if not data:
        print "Client has exited!"
        break
    else:
        print "\nReceived message '", L[1],"'"

# Close socket
UDPSock.close()
