python - Python:WAITING输入时打印数据

Question

编写一个聊天程序，并希望它能够打印接收到的消息，而用户可以向其他人输入消息。当前，程序将消息发送到另一台计算机，然后接收另一台计算机的消息，然后重复。

import sys
import socket as so
import platform
from socket import *
import string
import base64
import os
import random

dmi = 0
lmi = 0 
host = ""
checkcode = ''.join(random.choice('0123456789QWERTYUIOPLKJHGFDSAZXCVBNMasdfgjhklpoiuytrewqmnzbxvc') for i in range(16))
BLOCK_SIZE = 32
hostl = raw_input("> Input IP of computer message will be sent to: ")
port = 13000
buf = 1024
addr = (host, port)
addrl = (hostl, port)
UDPSock = socket(AF_INET, SOCK_DGRAM)
UDPSock.bind(addr)
addr = (host, port)
addrl = (hostl, port)
while dmi == 0:
    datal = raw_input("Enter message to send or type 'exit': ")
    UDPSock.sendto(datal, addrl)
    if datal == "exit":
        UDPSock.close()
        dmi +=1
    (data, addr) = UDPSock.recvfrom(buf)
    print "Received message: "+ data
print "Done!"

不要问我导入的不需要的库，这是一个测试脚本。

您需要学习如何使用多个线程(http://www.tutorialspoint.com/python/python_multithreading.htm)。一个线程等待用户输入，而另一个线程接收消息并打印。
