def thread_func(): while True:
#do something
#do something
#do somethingt=threading.Thread(target = thread_func)
t.start()# main thread do something
# main thread do something
# main thread do something
跑起来是没有问题的,但是使用ctrl + c中断的时候出问题了,主线程退出了,但子线程仍然运行。
于是在主线程增加了信号处理的代码,收到sigint时改变子线程循环条件
loop = True
def thread_func(): while loop:
#do something
#do something
#do somethingt=threading.Thread(target = thread_func)
t.start()# ctrl+c时,改变loop为False
def handler(signum, frame):
global loop
loop = False
t.join()
exit(0)
signal(SIGINT, handler)# main thread do something
# main thread do something
# main thread do something
这样ctrl+c就可以退出了,但是疑惑的是,主线程退出进程不会退出吗?
这里有个参考,讲线程deamon属性,可能于此相关,需要抽时间学习:
