Python 在原始输入（）内显示输出

我正在实现一个聊天服务器，目前我有一个客户端套接字列表，我想通过它发送信息，问题是客户端处于raw_input（）状态，以便通过服务器发送要转发的消息，并且每个客户端的缓冲区都被填满，直到该客户端本身在raw_input（）中输入内容为止字段，此时它将其接收缓冲区打印为单行块

我希望每个客户机都能立即显示其缓冲区中的内容，即使它们卡在raw_input（）中

以下是我的输出：

cli1.py

cli2.py

Your Message: test
Your Message: Received  "'test'"

因为（正如@thefourtheye所说）

raw\u input

是主线程上的一个I/O块，所以您需要创建一个单独的线程来打印消息

多线程解决方案：

>>> def print_message():
    time.sleep(5)
    print "message"


>>> bgThread = Thread(target=print_message)
>>> bgThread.start()
>>> x = raw_input()
message
input is entered here
>>> print x
input is entered here

---

使用单独的

线程

接收和打印消息

raw\u input

执行阻塞调用我该怎么办？还有什么选择？作为补充，我认为您没有正确使用

Thread

s。在您的客户机代码中，您为

iamclient（）

启动一个线程以运行一次，然后再次（无线程）运行多次。
