Python：如何在运行无限循环时从控制台获取输入？

Question

我正在尝试编写一个简单的Python IRC客户端。到目前为止，我可以读取数据，并且可以自动将数据发送回客户端。我在中获取数据while True，这意味着我无法在输入数据的同时读取数据。如何在控制台中输入仅在按Enter键时发送的文本，同时运行无限循环？

基本代码结构：

while True:
    read data
    #here is where I want to write data only if it contains '/r' in it

另一种方法涉及线程。

import threading

# define a thread which takes input
class InputThread(threading.Thread):
    def __init__(self):
        super(InputThread, self).__init__()
        self.daemon = True
        self.last_user_input = None

    def run(self):
        while True:
            self.last_user_input = input('input something: ')
            # do something based on the user input here
            # alternatively, let main do something with
            # self.last_user_input

# main
it = InputThread()
it.start()
while True:
    # do something  
    # do something with it.last_user_input if you feel like it
