Python的UDP通讯（收发一体、多线程）

想着自己做一个上位机，用labview的话还要装软件和驱动，用python装一个解释器就ok了比较省事，这个只是个dome！刚学python三个小时！若有错误请见谅，请指导，谢谢！代码如下！

from tkinter import *  # 导入tkinter文件库
from tkinter import Frame  # 库文件入口

def SendData():
    while True:
        Data = "这是UDP发送数据！"
        UdpSocket.sendto(Data.encode('gb2312'), (AddrIP, AddrPort))
        # print(AddrIP, AddrPort)
        time.sleep(1)


# ------------------------------ Recv() ----------------------------- #

        global text1
        TempData = UdpSocket.recvfrom(1024)
        # cur = datetime.datetime.now()  # 获取当前系统时间
        print("从[%s:%d]接收到了:%s" % (TempData[1][0], TempData[1][1], TempData[0].decode("GB2312")))
        text1.insert(END, TempData)
        # text1.insert(END, cur)
        text1.insert(END, "\n")  # INSERT索引表示插入光标当前的位置
