who can help me with computer science? (python turtle) I don't understand what code should be included in the missing code...output is at the bottom.

import turtle #creates the turtle and calls all other functions to create pixel art def main(): bob-turtle.Turtle() SC-turtle.Screen() drawSquare (bob, "pink", 20) drawSquare (bob, "orange", 20) newrow (bob,20,2) #draws a square of a size and color Iturtle should end bottom right corner facing east def drawSquare(t, color, size): t.fillcolor (color) for i in range (4): t. forward (size) #missing code #moves turtle from the end of a row to the beginning of new row def newrow (t, size, number): t.left (90) t. forward (size) #missing code t. forward (size*number) #calls main method main()
