Python Unit 2

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

• Will create a slinky with 5 circles

• Infinite Loop

Which command will Tracy perform when given the following code?

count = 200

count = count + 1

if count % 2 == 0:

forward(count)

backward(count)

• forward(201)

• backward(201)

• forward(200)

• backward(200)

What will be the output of the following program?

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

circle(50, 360, i)

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

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

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

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

Can a user’s input control the size of a circle? If so, how?

• No, user input is a string.

• Yes, circle(user_input=50)

• Yes, radius = int(input("Radius: "))circle(radius)

• Yes,radius = input("Radius: ")circle(radius)

What shape will be drawn with the following command?circle(50, 360, 3)

• Circle

• Triangle

• Diamond

• Square

Which of the following commands can be used to turn Tracy to face North if she is initially facing South?

• right(180)

• left(90)

  right(90)

• left(360)

• left(180)

  right(90)

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

for i in range(5): forward(10)

• 10

• 5

• 50

• 60

What does the number in the parentheses in a forward or backward command represent?

• How many degrees Tracy is supposed to turn

• How fast Tracy is supposed to move

• How many times Tracy should repeat the command

• How far Tracy is supposed to move

What control structure would be best to use in the following code?

backward(100)

right(90)

backward(100)

right(90)

backward(100)

right(90)

backward(100)

right(90)

• while loop

• if/else statement

• function

• for loop

How can we use variable to control the size of a circle?

• radius = 50

  circle(50)

• circle(radius)

  radius = 50

• radius = circle(50)

• radius = 50

  circle(radius)
