python关闭线程的方法:首先导入threading,定义一个方法;然后定义线程,target指向要执行的方法,启动它;最后停止线程,代码为【stop_thread(myThread)】。
python关闭线程的方法:
一、启动线程
首先导入threading
import threading
然后定义一个方法
- def serial_read():
-
- ...
-
- ...
然后定义线程,target指向要执行的方法
myThread = threading.Thread(target=serial_read)
启动它
myThread.start()
二、停止线程
不多说了直接上代码
- 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)
停止线程
stop_thread(myThread)
