子執行緒的強制性終止是我們實際應用時經常需要用到的，然而python官方並沒有給出相關的函式來處理這種情況。網上找到一個挺合理的解決方案，這裡分享給大家。

import threading
import time
import inspect
import ctypes
 
 
def _async_raise(tid, exctype):
    """raises the exception, performs cleanup if needed"""
    tid = ctypes.c_long(tid)
    if not inspect.isclass(exctype):
        exctype =
 
 type(exctype)
    res = ctypes.pythonapi.PyThreadState_SetAsyncExc(tid, ctypes.py_object(exctype))
    if res == 0:
        raise ValueError("invalid thread id")
    elif res != 1:
        # """if it returns a number greater than one, you're in trouble,
        # and you should call it again with exc=NULL to revert the effect"""
 

        ctypes.pythonapi.PyThreadState_SetAsyncExc(tid, None)
        raise SystemError("PyThreadState_SetAsyncExc failed")
 
 
def stop_thread(thread):
    _async_raise(thread.ident, SystemExit)
 
 
def test():
    while True:
        print('-------')
        time.sleep(0.5)
 
 
if __name__ == "__main__"
 
:
    t = threading.Thread(target=test)
    t.start()
    time.sleep(5.2)
    print("main thread sleep finish")
    stop_thread(t)
