Question Python Armstrong Number

Here's the mistake:
'>' is not supported between occurrences of 'int' and 'Entry'.
Here is my code:

Code (Text):

1. import re
2. from tkinter import *
3.  
4. root = Tk()
5.  
6. label = Label(root, text="Enter a 7 digit Number")
7. label.pack()
8.  
9. num = Entry(root, width=50, bg="orangered")
10. num.pack()
11.  
12. def myclick():
13.     Sum = 0
14.     temp = num
15.  
16.     if 1000 > num > 99:
17.         while temp > 0:
18.             digit = temp % 10
19.             Sum += digit ** 7
20.             temp //= 10
21.             if num == Sum:
22.                 label2 = Label(root, num, "is an Armstrong number")
23.                 label2.pack()
24.             else:
25.                 label3 = Label(root, num, "is not an Armstrong number")
26.                 label3.pack()
27.     else:
28.         label4 = Label(root,
29.                        "The number you entered is not a 7 digit number, Please Enter a number between 100 and 999")
30.         label4.pack()
31.  
32. MyButton = Button(root, text="Click", command=myclick)
33. MyButton.pack()
34. root.mainloop()

So, basically, I'm attempting to write a Python software that will determine whether or not the three-digit number supplied by the user is an Armstrong number. That works perfectly in Python, except that it prints the answer three times in the terminal. However when I use tkinter like in this documentation, I have some issues because I only learned about it a few hours ago and don't really know how to use it. The issue I'm having is with the > operator; I'm receiving data in Entry(), but the > operator is only for integers, therefore I'm getting type problems.

All I want is for this software to run in a graphical environment and to stop reporting the result three times. Can somebody assist me?
