[Tkinter] GUI Speed

[DPaul]

I sure can:

import random
from tkinter import *
import time

# GUI
root = Tk()
root.geometry('900x900+250+100')
root.title('Test')
root.configure(background='grey')
Kanvas = Canvas(root,width=900, height=900, bg='grey')
Kanvas.pack()    

colors = ('white','yellow','green','red')
def new_sit():
    for row in range(60):
        for col in range(60):
            color= random.choice(colors)
            y = row * 15 
            x = col * 15
            Kanvas.create_rectangle(x,y,x+15,y+15,fill=color)
    root.update()
    
steps = 0
while True:
    steps += 1
    Kanvas.delete('all')
    print(f'Step {steps}')
    new_sit() 
   
root.mainloop()
