TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'

I'm begining with some code as below:
from tkinter import *
top = Tk()
def spam():
for i in range(int(a1)):
print(i)
sbmitbtn = Button(top, text = "Login",activebackground = "Black", activeforeground = "white",command=spam).place(x = 40, y = 180)
a1 = Entry(top).place(x = 90, y = 60)
But when I run code, I got an error "TypeError: int() argument must be a string, a bytes-like object or a number, not 'NoneType'"
How can I fix it?

You should use
get()method to get the value of the Entry:for i in range(int(a1.get())): print(i)And replace:
a1 = Entry(top).place(x = 90, y = 60)To
a1 = Entry(top) a1.place(x = 80, y = 50)I hope it works for you.
