Question

The following program runs a math quiz consisting of 10 multiplication problems involving operands between 1 and 10:

import random

correct = 0

for i in range(10):
    num1 = random.randint(1, 10)
    num2 = random.randint(1, 10)
    prod = num1 * num2

    ans = int(raw_input("What is " + str(num1) + " times " + str(num2) + "? "))

    if ans == prod:
        print "That's right -- well done. "
        correct += 1
    else:
        print "No, I'm afraid the answer is ", prod, " "

print " I asked you 10 questions. You got ", correct, " of them right."
print "Well done!"

Please help me do the following:

Modify the program so that the user can choose how many questions they will be asked. Dont allow them to choose 0 or a negative number.

Add levels to the program:
o   Beginner - with operands between 1 and 10
o   Intermediate - with operands between 1 and 25
o   Advanced - with operands between 1 and 50
o   The user should choose the level when starting a quiz.

Modify the message at the end so that it says:
o   Well done! if the user answered more than 3/4 of the questions correctly.
o   You need more practice if they get between 1/2 and 3/4 of the questions correct.
o   Please ask your math teacher for help! if they get less than 1/2 of the questions correct.
(Round up if in doubt the user needs to answer 5 questions to get of 6 correct)

Allow the user to start another quiz without restarting the program.

Let the user choose the question type: addition, subtraction, multiplication, or mixed (randomly choose for each question).

This is in Python, using IDLE. If possible, please help me come up with a short, clean, and elegant solution.

Explanation / Answer

Sure!! I'll try my best to give a brief yet consistent solution!
