Computers cannot understand human languages such as English
A turtle starts in the middle of the screen. Where does the turtle finish after this program runs?
Back at its starting point

Count controlled loop
Which term describes the punctuation mark that must come at the end of the first line of a for loop?
Colon
What is the name for the spaces at the start of a line that show the code belongs inside a loop?
Indentation
In the line for i in range(5):, what does range(5) set?
How many times the indented code is repeated
Which keyword starts a count controlled loop in Python?
For
When a loop draws a regular shape, what name is given to the angle the turtle turns through at each corner?
Exterior angle
Why is a for loop useful when drawing a shape such as a hexagon?
It repeats the same lines instead of copying them
Which line correctly starts a for loop that repeats 4 times?
for i in range(4):
In a for loop, which lines of code are repeated?
The indented lines underneath the for line
To draw a regular shape with a loop, the turn each time should be which value?
360 divided by the number of sides
How many times must a loop repeat to draw a circle using forward(1) and right(1)?
360 times
A loop uses for i in range(2): and turtle.right(90) to draw a square, but only half a square is drawn. What is the fix?
Change range(2) to range(4)
A loop is written with empty brackets, as in range(). What will happen?
Nothing is drawn because no repeat count is given
When one loop draws three separate squares, why is penup() used between them?
To move into position without leaving a line
A pupil draws an octagon with for i in range(8): but uses turtle.right(4) inside the loop. The shape comes out wrong. Which turn should be used instead?
45 degrees
A pupil writes for i in range(4) but forgets the colon at the end of the line. What happens when the program runs?
The program stops with an error
Which term describes a named block of code that can be run whenever it is needed?
A subroutine
Which keyword is written at the start of a subroutine definition?
Def
What is meant by calling a subroutine?
Writing the name of the subroutine with brackets so the code inside it runs
Which term describes the pair of round symbols that must be written after a subroutine name at the end of the def line and again each time it is called?
Brackets
What is meant by defining a subroutine?
Writing a def line and the code that belongs to it
Which symbol must come at the end of the def line, after the brackets?
A colon
In the line def draw_star():, what is the name of the subroutine?
draw_star
Which line correctly starts the definition of a subroutine called draw_square?
Def draw_square():
Why is a subroutine useful when a program draws the same shape many times?
It removes repeated code and keeps the program short
A student defines a subroutine that draws a square, then runs the whole program. Nothing is drawn. What is the most likely reason?
The subroutine was defined but never called
A subroutine called draw_circle has already been defined. Which line calls it?
draw_circle()
How many times can a subroutine be called in a program?
As many times as needed, and it runs the same way each time
Why does the code inside a subroutine need to be indented?
It shows Python which lines belong to the subroutine
A subroutine called square contains a for loop that draws one square. What happens when square() is called three times?
Three squares are drawn, one from each call
A subroutine draws a square. A student wants to draw two squares in different places. What must be added between the two calls?
Lift the pen, move the turtle, then put the pen down again
A program defines draw_square(), and later has the line draw_square with no brackets. What happens when the program runs?
The subroutine is not called, so no square is drawn
A subroutine draw_square() draws one square. A student wants to draw four squares in a row. What is the best way to do this without repeating the square code?
Call draw_square() in a loop four times
What happens if the lines of code inside a subroutine are not indented?
They are not part of the subroutine
Which command sets the colour of the lines the turtle draws?

Which command changes how thick the lines drawn by the turtle are?
The command pensize()
What is meant by turtle.width()?
It changes how thick the lines are drawn, like pensize
A student types turtle.pencolour('blue') but the lines stay black. Why?
Python only knows the American spelling, pencolor
A student wants to fill a square with red. Which order of steps is correct?
Set the fill colour, begin the fill, draw the square, end the fill
A program draws a square but never calls turtle.end_fill(). What is the result?
The square is drawn but stays unfilled
A student's filled shape has colour leaking outside its edges. What is the most likely cause?
The lines of the shape do not join up
A student wants each side of a square in a different colour. What should they do?
Call pencolor before drawing each side
