What is the main benefit of using selection (if statements) in Python programming?

• It allows code to run faster
• It enables code to repeat actions multiple times
• It helps in making decisions based on conditions, allowing the code to choose different paths
• It simplifies the import of libraries

How does selection in Python use conditions?

• By checking if a variable is a specific data type
• By checking whether a condition is true or false, and then deciding which block of code to execute
• By looping through a list of items
• By importing different libraries based on the condition

Look at the code shown, what word starts the selection statement?

• for
• import
• input
• if

Look at the code shown, what does the selection statement (if statement) check for?

• Whether the turtle has drawn a square
• Whether the user wants to draw a square
• Whether the turtle is moving forward
• Whether the turtle's pen is down

Look at the code shown, what will happen if the user enters "no" to the question?

• The turtle will draw a square
• The turtle will draw a circle
• Nothing will be drawn
• The turtle will move backwards

Look at the code shown, why is there an elif statement included?

• To handle the case when the user enters an invalid shape
• To draw a pentagon if the user inputs 'pentagon'
• To check if the side length entered is a valid integer
• To handle the drawing of a rectangle if the user inputs 'rectangle'

Look at the code shown, what does the else statement do?

• It prints an error message if the user inputs an invalid shape
• It checks if the input shape is 'square' and draws it with the specified side length
• It draws a rectangle if the input shape is 'rectangle'
• It ensures the turtle object (pen) is properly initialised for drawing

Look at the code shown, if the user enters '1' for the number of sides, what will the turtle draw?

• A square
• A triangle
• A single line
• A circle

Look at the code shown, what will happen if the user enters '0' when prompted for the number of sides?

• The turtle will draw a single line
• The turtle will not draw anything
• The program will enter a loop
• The program will display a message stating that nothing will be drawn

Look at the code shown, if the user enters '5' for the number of sides, how does the program calculate the angle for each turn?

• Divide 360 by 5
• Multiply 360 by 5
• Divide 180 by 5
• Subtract 5 from 360
