进程：

感觉只是使用Process模块加以使用即可：

from socket import *
from multiprocessing import Process
from  time import sleep

    while True:
        recvData = newSocket.recv(1024)
        if recvData:
            print(‘recv[%s]:[%s]‘ %(str(destAddr),recvData.decode()))
        else:
            print(‘[%s]客户端已经关闭‘%(str(destAddr)))
            break
    newSocket.close()
def main():
    serSocket = socket(AF_INET,SOCK_STREAM)
    serSocket.setsockopt(SOL_SOCKET,SO_REUSEADDR,1)
    localAddr = (‘‘,7788)
    serSocket.bind(localAddr)
    serSocket.listen(5)
    try:
        while True:
            print(‘----主进程等待新客户端的到来---‘)
            newSocket,destAddr = serSocket.accept()
            print(‘---主进程接来下创建一个新的进程负责数据处理数据[%s]‘ %str(destAddr))
            client = Process(target=dealWithClient,args=(newSocket,destAddr))
            client.start()
            newSocket.close()
    finally:
        serSocket.close()
if __name__ == ‘__main__‘:
    main()
