I'm a beginner in Python, I need help. How to make the robot to choose 1, 2 or 3 and display it.

from tkinter import * from time import time import random

window = Tk() window.geometry('400x300')

sticks = 20

def computer(): global sticks

delete_sticks = random.randint(1, 3)
sticks = delete_sticks

def player(): global sticks

delete_sticks = int(entry_sticks.get())

if delete_sticks in [1,2,3]:
    sticks -= delete_sticks
    label_sticks.config(text="|"*sticks)
    status.config(text=sticks)
    if sticks == 1:
        status.config(text='YOU WON!', fg='Green')
    else:
        window.after(200, computer)
        Label_move.config(text='Computers turn, please wait.')
        

Label_move = Label(text='Type in a number from 1 to 3', font=('Arial', 15,'bold')) Label_move.pack()

emptyspace1 = Label() emptyspace1.pack()

entry_sticks = Entry(font=('Arial', 15,'bold')) entry_sticks.pack()

emptyspace2 = Label() emptyspace2.pack()

label_sticks = Label(text = sticks*'|', font = ('Arial', 30,'bold')) label_sticks.pack()

emptyspace3 = Label() emptyspace3.pack()

status = Label(text = '0', font=('Arial', 30, 'bold')) status.pack()

button = Button(text = 'Take sticks', font=('Arial', 15, 'bold'), command = player) button.pack()

window.mainloop()
