退出python线程的更多pythonic方法-daemon vs stop\u事件

以下代码:

import threading
import time
from functools import partial
from itertools import count

def daemon_loop(sleep_interval, stop_event):
    for j in count():
        print(j)
        if stop_event.is_set():
            break
        time.sleep(sleep_interval)
        print('Slept %s' % sleep_interval)
    print('Prod terminating')

if __name__ == '__main__':
    stop_event = threading.Event() #https://stackoverflow.com/a/41139707/281545
    target = partial(daemon_loop, sleep_interval=2, stop_event=stop_event)
    prod_thread = threading.Thread(target=target,
                                   # daemon=True
                                   )

    try:
        prod_thread.start()
        while True:
            time.sleep(10)
    except KeyboardInterrupt:
        print('Terminating...')
        stop_event.set()

C:\Users\MrD\.PyCharm2018.2\config\scratches>c:\_\Python363-64\python.exe thread_daemon.py
0
Slept 2
1
Terminating...
Slept 2
2
Prod terminating

取消注释 # daemon=True 行导致prod\u线程立即结束:

C:\Users\MrD\.PyCharm2018.2\config\scratches>c:\_\Python363-64\python.exe thread_daemon.py
0
Slept 2
1
Terminating...

我的问题是,处理线程终止的首选/更具python风格的方法是什么-我应该放弃事件机制并将线程标记为守护进程,还是遗漏了一些边缘情况?
