python3 如何实现实时聊天功能

[cyx441984694]

小白请教python3聊天室功能实现

代码来源：http://blog.csdn.net/calling_wisdom/article/details/42524745

用pycharm测试时候发现，Client那边，A输入一行字，B不能马上收到。需要B先打东西，然后才能收到A的信息。与此同时，A才能收到。
跪求大神解答。好像是threading的问题，还是说pycharm的问题？

Server:

#!/usr/bin/python3

Sock.listen(5)

def tellOthers(mynum,whatToSay):
    for c in mylist:
        if c.fileno() != mynum:
            try:
                c.send(whatToSay.encode())
            except:
                pass

def subThreadIn(myconnection,connNumber):
    nickname = myconnection.recv(BUFSIZE).decode()
    mydict[myconnection.fileno()]=nickname
    mylist.append(myconnection)
    print('Connection',connNumber,'has nickname:',nickname)
    while True:
        try:
            recveMsg=myconnection.recv(BUFSIZE).decode()

            print(mydict[connNumber],'exit,',len(mylist),'person left')
            tellOthers(connNumber,'[Remind:'+mydict[connNumber]+' has left the chatting room]')

然而我测试，客户端发送，服务器端会收到

你好，我测试过的是客户端那边不能实时同步。A,B都是客户端，需要等对方按了回车键才可以。是哪里有问题吗？

print(Sock.recv(BUFSIZE).decode())   ##这里先后顺序并没有差别的。
            Sock.send(myword)

谁告诉你顺序没有差别的？
