一、启动线程yxH少儿编程网-https://www.pxcodes.com

首先导入threadingyxH少儿编程网-https://www.pxcodes.com

import threading

然后定义一个方法yxH少儿编程网-https://www.pxcodes.com

def serial_read(): ... ...

然后定义线程，target指向要执行的方法yxH少儿编程网-https://www.pxcodes.com

myThread = threading.Thread(target=serial_read)

启动它yxH少儿编程网-https://www.pxcodes.com

myThread.start()

不多说了直接上代码yxH少儿编程网-https://www.pxcodes.com

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)
