在执行更多代码的同时保持一些代码运行 [英] Leave some code running while executing more

问题描述

我正在python中启动一个循环，在启动循环后，我希望在循环之后继续执行代码，同时循环保持循环(在背景"中).

I am starting a loop in python, and after I start the loop I want the execution of code after the loop to carry on, while the loop keeps looping (in the 'background').

x=True

while x:
  #do some output
  sleep(1)

#ask for input or something
if input()=='something':
  x=False

因此在该示例中，#do some output将在请求输入时不断发生.

So in that example, #do some output will keep happening while input is asked for.

这在python中可能吗?是否有任何变通办法可以实现这一目标?

Is this possible in python? Are there any work-arounds that could achieve this?

推荐答案

按照OP的要求，我发布了答案. :)有多个库可以实现您要尝试执行的操作.最知名的包括:

Following OP's wish I'm posting the answer. :) There are multiple libraries for achieving what you are trying to do. Most known include:

• 线程模块
• 多重处理模块

• threading module
• multiprocessing module

它们之间有细微的差别，但是我想您现在不必担心这一点.我鼓励您尽管阅读更多有关多线程处理和线程的一般信息.另外，绿色"线程是一个有趣的替代方法.

There are subtle differences between them, but I guess that you shouldn't worry about it at the moment. I encourage you though to read more about mutli-processing and threading in general. Also "green" threads is an interesting alternative.
