CMU Unit 2

What is the only shape property that cannot be changed once it has been set?

• opacity

• align

• roundness

• radius

What will the following code do?

def g (color):

• Rect (200, 200, 100, 300., fill = color)

g( )

• a rectangle with a fill of NONE

• a blue rectangle

• a rectangle with a random color

• It will give an error message

What will happen in the following code?

f()

def f():

Circle(200, 200, 50, fill='purple')

• You will get an error

• A purple circle

• An empty circle

• A purple oval

In onMousePress, we can get a point to the right of the mouse press by

• adding a positive number to the mouseY

• adding a negative number to the mouseX

• adding a positive number to the mouseX

• adding a negative number to the mouseY

What happens when the mouse is pressed?

s =Star(200, 200, 50, 6, fill="yellow)

def onMousePress(mouseX, mouseY):

s.points = 8

• the color of the star will change

• The radius will change to 8

• It will draw a 6 sided star

• The points will change from 6 to 8

What will happen when the mouse is released?

def onMouseRelease(x,y):

Oval(x, y, 150, 150, fill='blue')

Circle(x, y, 10, , fill='green')

• A green oval on top of a blue circle

• A green circle on top of a blue oval

• A blue oval on top of a green circle

• A blue oval next to a green circle

This question uses the following functions.

def drawStar(x, y):

Star(x, y, 50, 5, fill='mediumSlateBlue')

def drawCircles(x):

Circle(x - 30, 200, 50, fill='limeGreen')

Circle(x + 30, 200, 50, fill='limeGreen')

In what order do you need to call the functions to create this picture?

• drawStar(275, 150)

  drawCircles(125) drawCircles(275) drawStar(125, 250)

• drawCircles(125) drawCircles(275) drawStar(275, 150) drawStar(125, 250)

• drawStar() drawCircles()

• drawStar(275, 150) drawCircles(125) drawStar(125, 250)
