how to display entry widget on new window in tkinter?

Question

from tkinter import *
from tkinter import messagebox

w = Tk()

w.geometry('200x250')

def buttons():
    r1 = Tk()
    r1.geometry('200x250')
    r1.mainloop()





t= Label(text = "MIB",font =("Arial", 49))
t.pack(side = TOP)

e = Label(text = "Email")
e1 =Entry()

e.pack()
e1.pack()

p = Label(text = "Password")
p.pack()

p1 = Entry()
p1.pack()

b= Button(text = "SIGN UP", command = buttons)
b.pack()
w.mainloop()

How I can display the entry widget after clicking submit button in the new window in tkinter python? I tried defining under button function but it is showing me the window but not the widgets. The widgets are only displayed on the first window after clicking submit button.

TK() is the root window, so it needs to be called only once. After that, to open another window, you need to use tkinter.Toplevel(). Below is the code I put labelexample in a new window.

from tkinter import *
from tkinter import messagebox

w = Tk()

w.geometry('200x250')

def buttons():
    r1 = Toplevel(w)
    r1.geometry('200x250')
    labelexample = Label(r1, text = 'GOOD')
    labelexample.pack()

t= Label(text = "MIB",font =("Arial", 49))
t.pack(side = TOP)

e = Label(text = "Email")
e1 =Entry()

e.pack()
e1.pack()

p = Label(text = "Password")
p.pack()

p1 = Entry()
p1.pack()

b= Button(text = "SIGN UP", command = buttons)
b.pack()
w.mainloop()
