import random

##Ask the username and welcome the user

print('Welcome to my Maths Quiz!!!')
username = input('What is your username? ')

##Start the program

def script():
    

    while True:
        try:
            question_num = int(input('How many questions do you want? (0-15) '))
            if question_num < 1 or question_num > 15:
                print('Please enter a number between 0 and 15')
            else:
                break
        except ValueError:
            print('Invalid input. Please enter a whole number.')
            
    print(f"Ok! Good Luck {username}!")

##Determine the random numbers

    question_marker = 0
    score = 0

    history_list = []

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


       
##Ask the user the first question

        while True:
            try:
                answer = int(input(f'{question_marker}: 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:
            message_result = 'You got it right!!' 
            print(message_result)
            score += 1
        elif answer < correct_answer:
            message_result = f'Too low!!! The answer is {correct_answer}.'
            print(message_result)
        else:
            message_result = f'Too high!!! The answer is {correct_answer}.'
            print(message_result)

        history_list.append(message_result)

##Display percentage

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

##Ask if the user wants to see their history

    see_history = input('Do you want to see your quiz history? ')
    if see_history == 'yes' or see_history == 'y':
        print(*history_list, sep='\n')

##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.')
    
##Close the program

script()
