python關閉線程的方法:首先導入threading,定義一個方法;然后定義線程,target指向要執(zhí)行的方法,啟動它;最后停止線程,代碼為【stop_thread(myThread)】。

python關閉線程的方法:
一、啟動線程
首先導入threading
import threading
然后定義一個方法
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)
