Unit 2 - Turtle Graphics Quiz for Python Computer Programming I

When the following for loop is complete, how many spaces will Tracy have moved?

for i in range(5):

forward(10)

• 10 spaces

• 50 spaces

• 5 spaces

• 5 spaces

Suppose you write a function. How many times can you call the function in your code?

• As many times as you want

• It depends on the function

• Not more than the number of commands the function holds

• Once

In which of the following situations would it be best to make a function?

• You need Tracy to move forward by 100.

• You need to change Tracy’s color.

• You want Tracy to draw a blue line, and your program requires lots of blue lines.

• You need Tracy to turn right and then turn left.

Which command will Tracy perform when given the following code?

count = 5

count = count * 2

if count < 10:

forward(count)

elif count < 20:

backward(count)

else:

circle(count)

• forward(10)

• circle(10)

• backward(10)

  circle(10)

• backward(10)

What will be the output of the following code?

count = 5

while count > 0:

circle(50)

forward(100)

• 5 circles in a row

• 4 circles in a row

• An infinite loop will occur

• A slinky with 5 circles

Which command will Tracy perform when given the following code?

count = 200

count = count + 1

if count % 2 == 0:

forward(count)

backward(count)

• forward(200)

• backward(201)

• backward(200)

• forward(201)

Which of the following pieces of code will make Tracy do the following actions three times: go forward, change colors, and then turn around.

• forward(30)

  color("blue")

  left(180)

  
  

  forward(30)

  color("green")

  left(180)

  
  

  forward(30)

  color("orange")

  left(180)

• for i in range(4):

  forward(30)

  color("blue")

  left(180)

• for i in range(3):

  backward(30)

  color("blue")

  left(180)

• for i in range(3):

  forward(30)

  color("blue")

  left(180)

  color("red")

Suppose you want to make Tracy draw a mountain range, like the one shown above, starting from the left side.

Which of the following functions would be the most useful function to write in order to solve this problem?

• # Has Tracy draw a single triangle

  def make_triangle():

• # Draws a square

  def my_function():

• # Change's Tracy's color to red

  def change_to_red():

• # Moves Tracy forward by 100

  def move_100():

What will be the radii of the circles drawn from the following code?

for i in range(10, 55, 10):

circle(i)

• 10, 15, 20, 25, 30, 35, 40, 45, 50, 55

• 10, 20, 30, 40, 50, 55

• 10, 20, 30, 40, 50

• 10, 55, 10

What will be the output of the following program?

for i in range(3, 7, 2):

circle(50, 360, i)

• Two shapes- a triangle (3 sides) and a pentagon (5 sides).

• Three circles with radii of 3, 7 and 2.

• Three shapes- a triangle (3 sides), a pentagon (5 sides), and a heptagon (7 sides).

• Three shapes- a triangle (3 sides), a heptagon (7 sides), and a line (2 sides).
