The program is Python

2.1 Stairs 2.1.1 DrawSquare Create a function called drawSquare, which takes in a turtle and a number called square Size and uses that turtle to draw a square with each side squareSize pixels long. Your function should start like this: # myTurtle is the turtle doing the drawing # size is the length of each of the sides of the square. def drawSquare (myTurtle, squareSize): pass 2.1.2 Drawing a Row of Squares Write a function called drawRow that draws a row of squares. drawRow should call (use) drawSquare to accomplish this task. See the comments in the code for more details. # draws a row of squares # myTurtle is the turtle doing the drawing # length is how many squares are in the row # squareSize is the length of each of the sides of each square. def drawRow(myTurtle, length, squareSize): pass Figure 1: The output of drawRow(bob,5,50). 2.1.3 Drawing a Grid Write a function called drawGrid that draws a square grid of squares. drawGrid should call (use) drawRow to accomplish this task. See the comments in the code for more details. # myTurtle is the turtle doing the drawing # the grid will be "size" squares wide and "size" squares tall # squareSize is the length of each of the sides of each individual square. def drawGrid(myTurtle, size, squareSize): pass Figure 2: Output of drawGrid(bob,5,50). 2.1.4 Drawing a Stair of Squares Write a function called drawSquareStairs that draws a staircase made of squares, like in Figure 3. drawSquareStairs should call (use) drawRow to ac- complish this task. See the comments in the code for more details. # myTurtle is the turtle doing the drawing # height is how tall the stairs are going to be # squareSize is the length of each of the sides of each square. def drawSquareStairs (myTurtle, height, squareSize): Figure 3: Output of drawSquareStairs (bob,5,50)
