python使用tkinter编写一个数据显示窗口（实时显示更新的数据）
以下代码分为python3版本与python2版本，
python3版本主要靠
self.main_window.after( 刷新的时间毫秒, 需要刷新的函数这里为窗口的清除与插入函数) 刷新函数进行 ，
python2版本则通过编写一个线程进行刷新作用，刷新函数在python2 环境下会报错…
至于我为什么知道python2会出现这个问题，那就是ros没python3的版本…
示意图
(数据就会在后面的框里面通过程序运行时的值的改变而改变)：
python3版本
不解释了直接可以运行，运行效果为不断的刷新一号测距仪的值

python2版本
以下为代码，我这里在下面提供两个代码示例:
1.（第一部分）修改为可以直接运行显示，但注释掉了刷新数据的线程部分的，无法对数据进行更新。
"""注意这个 窗口拉起接口在 一 二 部分中被调用的不同的写法"""
self.main_window.mainloop()
2.（第二部分）没有注释掉线程部分，需要通过 from import 的方法在另外一个py文件的线程中进行调用更新，下面是我截取的部分在另一个py文件中的调用，示例
from hint_window import m_win
def t_correct(self):
t_correct = threading.Thread(target=self.calculate_instant_speed)
t_correct.setDaemon(True)
t_correct.start()
def calculate_instant_speed(self):
"""用于更新瞬时速度"""
"""
self.x_speed ,self.y_speed, self.p_speed
"""
m_win.updata_node("vx", self.x_speed)
m_win.updata_node("vy", self.y_speed)
m_win.updata_node("vw", self.p_speed)
