问题描述

我是一个没有经验的python程序员.

I'm an inexperienced python programmer.

是否可以使用backgroundworker，使其在程序启动时启动，并在程序关闭时关闭?

Is there a way to use the backgroundworker so that it starts at program startup and closes when program close?

我希望它观看一个按钮，按下该按钮将返回1.因此，当程序运行时只要button = 1 button都必须执行"this"操作.

I want it to watch a button, the button returns 1 when pressed. So while the program in running whenever button = 1 button has to do "this".

有人可以帮我吗?

推荐答案

有意义的是在您的主程序中启动一个单独的线程，并在后台执行任何操作.作为示例，请检查以下相当简单的代码:

Would make sense to start a separate thread within your main program and do anything in the background. As an example check the fairly simple code below:

import threading
import time

#Routine that processes whatever you want as background
def YourLedRoutine():
    while 1:
        print 'tick'
        time.sleep(1)

t1 = threading.Thread(target=YourLedRoutine)
#Background thread will finish with the main program
t1.setDaemon(True)
#Start YourLedRoutine() in a separate thread
t1.start()
#You main program imitated by sleep
time.sleep(5)
