Answer 1

If you generate your numbers like this:

larger_number = ''.join(random.sample(string.digits, 5))

And got the numbers from the user like this:

def get_user_num(length=5):
    while True:
        num = raw_input('Enter a {}-digit number with no repeating digits: '.format(length)).zfill(length)
        if len(set(num)) < length:
            print('Please try again.')
            continue
        else:
            return num

You could determine if the user's numbers were in the number list like so:

set(user_number) < set(larger_number)

And then it would be a really simple matter to combine this all together into a program. Note that the numbers are never actually treated as numbers - they're just strings.
