Question 1

How does the program handle invalid user input, and what happens to the game state when the user enters an invalid expression?

Answer 1

If the input is invalid, CheckIfUserInputValid() returns False, and the program deducts a point from the score.
- targetlist and numbers allowed remain unchanged

Question 2

How does the program manage the Targets list throughout the game, and what is the significance of updating and removing targets from the list?

Answer 2

• The Targets list represents the goals the player needs to achieve. Each time a target is hit, it is removed by setting it to -1
• Updating the target list allows new targets to be added, while previously hit targets are marked as completed
• This ensures that the player has new targets to reach as they progress through the game

Question 3

What is the role of the NumbersAllowed list, and how is it updated throughout the game? What happens if a user tries to use a number not in the allowed list?

Answer 3

• NumbersAllowed list represents the numbers that the user can use to form valid expressions.
• Whenever a user uses a number from this list in a valid expression, that number is removed from NumbersAllowed for the next round.
• If a user tries to use a number that is not in NumbersAllowed, the program will reject the input

Question 4

Explain the process that occurs when the game is over. How is the final score displayed, and what condition causes the game to end?

Answer 4

• The game ends when all the targets are completed, which is indicated by the first target being set to -1.
• When this condition is met, GameOver is set to True, and the game loop terminates. The final score is then displayed using the DisplayScore() function.
