What will be the output of the following Python code?

• A square filled in with the colour green

• A square outlined with the colour green

• Blank canvas

• Error

Answer explanation

The output shape of the code shown above is a square, outlined with the colour green, but not filled in with any colour. This is because we have not used the command t.end_fill() at the end.

• South

• East

• West

The command used to set only the x coordinate of the turtle at 45 units is:

• reset(45)

• setx(45)

• xset(45)

• xreset(45)

Which of the following functions returns a value in degrees, counterclockwise from the horizontal right?

• heading()

• degrees()

• position()

• window_height()

What will be the output of the following Python code?

import turtle

t.right(90)

t.forward(100)

print(t.heading())

• 0.0

• 90.0

• 270.0

• 360.0
