I have created the following image via Python script.

The script is as follows

import turtle t = turtle.Turtle() t.speed(0) t.pensize(3) side_length = 20 for i in range(5): t.penup() t.goto(-side_length/2, -side_length/2) t.pendown() for j in range(4): t.forward(side_length) t.left(90) side_length += 20 wn = turtle.Screen() wn.bgcolor("lightgreen") turtle.done()

How should I modify the script, to get this image instead?
