Project Euler: Problem 1

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.

all_numbers = range[:1000]
multiples = []

for variable in all_numbers:
    if variable %3 == 0 or variable %5 == 0:
        multiples.append

print multiples.sum
