pythondaemondaemon=True的含义，作为后台线程，False作为前台线程，与C#前后台线程含义相同，与java相同；参考其他博客：https://laike9m.com/blog/daem...,97/当所有python前台线程执行完后，进程退出，不管有没有后台线程；后台线程一般做心跳，等主线程结束了，就没有意义了；主线程默认为前台线程，创建子线程时，子线程的daemon参数继承父线程；gevent中的守护进程场景；gevent.spawn创建的协程都是后台协程，即daemon=True；前台协程；python如何杀死协程：gevent.killpython3如何杀死线程的参考链接：https://www.geeksforgeeks.org...在python线程中引发异常异常，如果需要执行清理"""tid=ctypes.c_long(tid)ifnotinspect.isclass(exctype):exctype=type(exctype)res=ctypes.pythonapi.PyThreadState_SetAsyncExc(tid,ctypes.py_object(exctype))ifres==0:raiseValueError("invalidthreadid")elifres!=1:#"""如果它返回一个大于一的数字，你就有麻烦了，#你应该可以使用exc=NULL再次调用它以恢复效果"""ctypes.pythonapi.PyThreadState_SetAsyncExc(tid,None)raiseSystemError("PyThreadState_SetAsyncExcfailed")defstop_thread(thread):_async_raise(thread.ident,SystemExit)deftest():whileTrue:print('--------')time.sleep(0.5)if__name__=="__main__":t=threading.Thread(target=test)t.start()time.sleep(5.2)print("mainthreadsleepfinish")stop_thread(t)Set/ResetstopflagUsingtracestokillthreadsimportsysimporttraceimportthreadingimporttimeclassthread_with_trace(threading.Thread):def__init__(self,*args,**keywords):线程。Thread.__init__(self,*args,**keywords)self.killed=Falsedefstart(self):self.__run_backup=self.runself.run=self.__run线程.Thread.start(self)def__run(self):sys.settrace(self.globaltrace)self.__run_backup()self.run=self.__run_backupdefglobaltrace(self,frame,event,arg):如果event=='call':returnself.localtraceelse:returnNonedeflocaltrace(self,frame,event,arg):ifself.killed:ifevent=='line':print('lineexit')raiseSystemExit()returnself.localtracedefkill(self):self.killed=Truedeffunc():whileTrue:print('threadrunning')time.sleep(1)t1=thread_with_trace(target=func)t1.start()time.sleep(2)t1.kill()t1.join()ifnott1.isAlive():print('threadkilled')使用多处理模块杀死threadsKillingPython线程通过将其设置为守护进程使用隐藏函数_stop()，这种方法无效
