How to get for loop to work with my code

As the subject says. I’ve been trying to understand how to get the for loop to work with my code, but I can not for the life of me figure it out. I have spent the past 2 hrs trying to get it but I just can not understand it. Can anyone help me with this code to get the for loop to work?

import turtle
wn = turtle.Screen()
tower = turtle.Turtle()
tower.color(“blue”)
tower.pensize(10)
side1 = 90
side2 = 40
side3 = 50
side4 = 60
#Right side of shape
tower.forward(side3)
tower.left(side1)
tower.forward(side2)
tower.left(side1)
tower.forward(20)
tower.right(side1)
tower.forward(side3)
tower.left(side1)
tower.forward(30)
tower.right(side1)
tower.forward(side4)
#Top of shape
tower.left(side1)
tower.forward(side2)
#Left side of shape
tower.left(side1)
tower.forward(side4)
tower.right(side1)
tower.forward(30)
tower.left(side1)
tower.forward(side3)
tower.right(side1)
tower.forward(20)
tower.left(side1)
tower.forward(side2)
#Bottom of shape
tower.left(side1)
tower.forward(side1)

wn.exitonclick()

Hi Krypto,

What do you want the for loop to do? You have given us a great chunk of
code, but no hint or clue as to where you want the for loop to go, what
you want it to do, or why you want it.

It might help if you show us one of your attempts to use a for loop, so
we can see what you are trying to do, and perhaps suggest how to fix it.
