Python:如何在运行无限循环时从控制台获取输入? [英] Python: How to get input from console while an infinite loop is running?

问题描述

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.我正在while True中获取数据，这意味着在读取数据的同时无法输入文本.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?

I'm trying to write a simple Python IRC client. So far I can read data, and I can send data back to the client if it automated. I'm getting the data in a while True, which means that I cannot enter text while at the same time reading data. How can I enter text in the console, that only gets sent when I press enter, while at the same time running an infinite loop?

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

推荐答案

另一种实现方法涉及线程.

Another way to do it involves threads.

import threading

# define a thread which takes input
class InputThread(threading.Thread):
    def run(self):
        self.daemon = True
        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
