Project Eular : Problem 1

                 Problem 

If we list all the natural numbers below 10 that are multiples of 3 or 5, we get 3, 5, 6 and 9. The sum of these multiples is 23.
Find the sum of all the multiples of 3 or 5 below 1000.

                 Solution

Python :

def solve():

    sum = 0

    for x in range(1000):

        if((x%3==0) or (x%5==0)):

            sum += x

    return sum

if __name__ == "__main__":

    print(solve())
