我想按下按钮在另一个窗口上显示标签

Question

我是python 3.5的初学者。我想按下按钮在另一个窗口上显示标签。下面是我正在尝试但无法实现的代码。请有人帮忙。提前致谢。

from tkinter import *
root = Tk()

def Proceed_button():
    proceed = Tk()
    Label(proceed, text="HI")

B1 = Button(root, text ="Proceed", justify = CENTER, font=("Times", "12",   "bold"), background = "yellow", command = Proceed_button).place(x=950,y=300)
