Sum of a range? : I am very new to Python. I am trying to find the sum of all numbers less that 1000 divisible by 3 and 5. I have this so far:

```for i in range(0, 1000):
    if i % 3 == 0:
        print i
    elif i % 5 == 0:
        print i
b = sum(i)
print b```

I get a TypeError: 'int' object is not iterable (referring to b = sum(i))
