Having some trouble with this python problem. I know how to make the square, I know how to loop the square, just dont know how to make it look like the picture ( expand to the left, Im assuming its the step=4). Heres the problem.

Write a Python turtle graphics program that uses nested loops to draw 100 squares, to create the design below.

STARTING_X = 150

STARTING_Y = -150

STARTING_SIZE = 8

NUM_SQUARES = 100

STEP = 4

NUM_SIDES = 4

ANGLE = 90
