Exercise:

• Write a function to find the sum of numbers in number plate for numerology

9999 => 9 + 9 + 9 + 9 => 36 => 3 + 6 => 9
8273 => 8 + 2 + 7 + 3 => 20 => 2 + 0 => 2

• solution

def sum_digits(number):
    sum = 0
    while number > 0:
        digit = number % 10 
        sum = sum + digit
        number = number // 10
        if number == 0 and sum > 9:
            number = sum
            sum = 0
    return sum
