what is the turtle module code for the below output by using the main method? (def)

how do I update the main method to continue the code?(at the bottom)

import turtle def main(): bob=turtle. Turtle() #sc = turtle.Screen() drawSquare (bob, "blue", 20) drawSquare (bob, "red", 20) drawSquare (bob, "yellow", 20) bob.right (90) bob.right (90) bob. forward (20) bob. forward (20) bob. forward (20) bob.right (90) bob.right (90) def drawSquare(t,color,size): t.fillcolor (color) t.begin_fill() for i in range (4): t. forward (size) t.right (90) t. forward (size) t.end_fill() def newRow(t, size, number): t.left(90) t. forward(size) t. forward (size* number) main()
