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 inspectimport ctypesdef _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)
