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.

# YOUR CODE HERE
sum=0
for i in range(1000):
    if i%3 ==0 or i%5==0:
        sum=sum+i
    i=i+1
print (sum)
