python關(guān)閉線程的方法：首先導(dǎo)入threading，定義一個(gè)方法；然后定義線程，target指向要執(zhí)行的方法，啟動(dòng)它；最后停止線程，代碼為【stop_thread(myThread)】。

本教程操作環(huán)境：windows7系統(tǒng)、python3.9版，DELL G3電腦。

python關(guān)閉線程的方法：

一、啟動(dòng)線程

首先導(dǎo)入threading

import threading

然后定義一個(gè)方法

    def serial_read():    ...    ...

然后定義線程，target指向要執(zhí)行的方法

myThread = threading.Thread(target=serial_read)

啟動(dòng)它

myThread.start()

二、停止線程

不多說了直接上代碼

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)

停止線程

stop_thread(myThread)
