import random
print('Welcome to my Maths Quiz!!!')
username = input('What is your username? ')
def script():
    

    while True:
        try:
            question_num = int(input('How many questions do you want? (0-50) '))
            if question_num < 1 or question_num > 50:
                print('Please enter a number between 0 and 50')
            else:
                break
        except ValueError:
            print('Invalid input. Please enter a whole number.')
            
    print(f"Ok! Good Luck {username}!")

##Determine the random numbers
    score = 0

    for question in range(question_num):
        num_1 = random.randint(1, 10)
        num_2 = random.randint(1, 10)
        correct_answer = num_1 * num_2

       
##Ask the user the first question

        while True:
            try:
                answer = int(input(f'What is {num_1} x {num_2}? '))
            
                if answer < 0 or answer > 100:
                    print('Please enter a number between 1 and 100.')
                else:
                    break
            
            except ValueError:
                print('Invalid input. Please enter a whole number.')
            


##Check input verses the correct answer

        if answer == correct_answer:
            print('You got it right!!')
            score += 1
        elif answer < correct_answer:
            print(f'Too low!!! The answer is {correct_answer}.')
        else:
            print(f'Too high!! The answer is {correct_answer}.')


    percentage = (score / question_num) * 100
    print(f'Your score is {score}/{question_num} which is {percentage}%')

##Restart the program

    restart = input('Would you like to restart the program? (y/n) ')
    if restart == 'yes' or restart == 'y':
        script()
    elif restart == 'no' or restart == 'n':
        print('Script terminating. Goodbye.')
    else: print('Invalid choice. Terminating program.')
    

script()
