python-3.x - 如何不开窗(How to not open window)

Question

from tkinter import *

def firstPage():
    def goSecond():
        root.destroy()
        secondPage()

    root = Tk()

    text = Label(root, text="1")
    text.pack()
    btn = Button(root, text="go to 2", command=goSecond)
    btn.pack()

    root.mainloop()

def secondPage():
    def goFirst():
        root.destroy()
        firstPage()

    root = Tk()

    text = Label(root, text="2")
    text.pack()

    btn = Button(root, text="go to 1", command=goFirst)
    btn.pack()

    root.mainloop()

firstPage()

I made this code and I want it to open a new page, but it open a new window, I understand why but I don't know how to open a page instead of open a window.

(我编写了此代码，并希望它打开一个新页面，但是它打开了一个新窗口，我知道为什么，但是我不知道如何打开页面而不是打开窗口。)
