55 - Python Basics 6

Written by Emily Leng

Problem

Given an integer value stored in args[0], find the sum of all numbers less than or equal to args[0] and greater than zero that are divisible by 7. Then, print the sum of all the digits of the original sum to get your answer.

Hint

What is a math operation to check divisibility?

Solution

tmp = 0
for i in range(7, args[0]):
    if i % 7 == 0:
        tmp += i

digits = 0
while tmp:
    digits += tmp % 10
    tmp /= 10

print digits
