So at number six in, Advanced topics in Python, their is a fairly easy project telling you to take the numbers 1-10 square them and see if they are divisible by four. If they are you put them into a list, easy.

```
cubes_by_four = [ n**2 for n in range(1,11) if n**2 % 4 == 0]
print cubes_by_four
```

answers

[4, 16, 36, 64, 100]

So you might be asking what is the problem, this is`It looks like your list has the wrong value at index 0. It should be 8.`

The first square that is divisible by four is 2 by 2 not 2.8 by 2.8
