python线程怎么销毁

python线程如何销毁
大家好，请教个python线程销毁的问题 伪代码大概如下：

class UDPListenThread(threading.Thread):

    def __init__(self,window,sockets,isav_or_feedback):

        threading.Thread.__init__(self)

        self.window = window

        self.socket = sockets

        self.timeToQuit = threading.Event()

        self.timeToQuit.clear()

        self.data=''

        self.udp_addr = ''

        self.isav_or_feedback = isav_or_feedback

    

    def run(self):      

        while True:

            if self.isav_or_feedback == 2 and self.window.sentFeedbackResponse == 1:

                    sleep(1)

            else:

                data,addr = self.socket.recvfrom(2048)

                self.udp_addr = addr

                if not data:

                    break

                else:

                    wx.CallAfter(self.window.SetUdpClientAddress,addr)      

                if self.isav_or_feedback == 1 and self.window.sentAVApplyResponse == 1:

                    self.sendAVStream()            

        self.socket.close()

            

    def stop(self):

        print 'close UDP socket'

        self.socket.close()

        self.timeToQuit.set()

             

    def sendAVStream(self):

        file_object = open('record.ts', 'rb')

        length = 0

        i = 0

        a_length = 0

        try:

            while True:

                chunk = file_object.read(940)

                if not chunk:
