无法在Windows上使用键盘Ctrl+C中断线程化Python控制台应用程序

您将线程设置为守护进程,但还需要保持“主”线程处于活动状态,以侦听信号或键盘中断

使用信号的简单工作实现:

import threading
import time
import sys
import signal

class FooThread(threading.Thread):
    def __init__(self):
        threading.Thread.__init__(self)

    def run(self):
        while not self.stop_flag:
            print(1)
            time.sleep(1)

    stop_flag = False

def main():
    t = FooThread()
    def signal_handler(signal, frame):
        print('You pressed Ctrl+C!')
        t.stop_flag = True
        t.join()

    signal.signal(signal.SIGINT, signal_handler)
    t.start()

    while not t.stop_flag:
        time.sleep(1)

if __name__ == "__main__":
    main()
