在python中启动和关闭线程： 一、启动线程 首先导入threading
代码语言：javascript复制import threading然后定义一个方法
代码语言：javascript复制 def serial_read():
...
...然后定义线程，target指向要执行的方法
代码语言：javascript复制myThread = threading.Thread(target=serial_read)启动它
代码语言：javascript复制myThread.start()二、停止线程 不多说了直接上代码
代码语言：javascript复制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
代码语言：javascript复制stop_thread(myThread)
