You may notice that entering a non-numeric value and clicking the ‘Check!’ button will cause a run-time error on the console. Therefore, your second task is to improve the application developed in Task 1 to ensure the user is only allowed to supply valid input values, i.e. a 4/5 number between 1 and 10 (inclusive). The application must still function as specified in Task 1 although you may remove the ‘Check!’ button if you wish

Thank you for your question. Based on your statement, I understand that you want me to improve an application developed in Task 1 to ensure that users can only input valid values, i.e., a 4/5 number between 1 and 10 (inclusive).

To achieve this, I can add input validation to the existing code. Here's how I would do it:

1. First, I would remove the 'Check!' button as you suggested since it is no longer necessary.

2. Next, I would modify the existing code to prompt the user to enter a valid input if they enter an invalid value. For example, if the user enters a value that is not a number or is not between 1 and 10, the program will display an error message and ask the user to enter a valid input.

3. Finally, I would implement a loop that will continue to prompt the user to enter a valid input until they do so. Once the user enters a valid input, the program will proceed with the calculations as specified in Task 1.

Here's a sample code snippet that demonstrates how I would implement the input validation:

while True:
    try:
        x = int(input("Please enter a 4/5 number between 1 and 10 (inclusive): "))
        if x >= 1 and x <= 10 and (x == 4 or x == 5):
            break
        else:
            print("Invalid input! Please enter a valid 4/5 number between 1 and 10 (inclusive).")
    except ValueError:
        print("Invalid input! Please enter a valid 4/5 number between 1 and 10 (inclusive).")

# Perform calculations using valid input value x

This code will keep prompting the user to enter a valid input until they do so. Once a valid input is entered, the code will proceed with the calculations as specified in Task 1. I hope this helps!
