Multiples of 3 and 5

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.
def run(limit=1000):
    return sum([x for x in range(limit) if x % 3 == 0 or x % 5 == 0])
