python - 通过 CTRL+C 中断所有线程

Question

当我按 CTRL+C 中断程序时，它仅退出主线程，而新创建的线程仍在工作。如何终止所有线程？

import threading, time

def loop():
    while True:
        print("maked thread")
        time.sleep(1)

t = threading.Thread(target = loop)
t.start()

while True:
    print("loop")
    time.sleep(1)

Answer 1

您可以使用标志并让线程检查标志是否退出，而在主线程中，您应该捕获KeyboardInterrupt异常并设置标志。

import threading, time
import sys

stop = False

def loop():
    while not stop:
        print("maked thread")
        time.sleep(1)
    print('exiting thread')

t = threading.Thread(target = loop)
t.start()

try:
    while True:
        print("loop")
        time.sleep(1)
except KeyboardInterrupt:
    stop = True
    sys.exit()
