I am having trouble with the returning of the numbers in the functions.

Its supposed to return false, but codecademy returns the error message:' by_three(1) returned 1 instead of False'

```
def cube(number):
return number**3
def by_three(number):
if (number / 3 ==0):
return cube(number)
else:
return False
```

Anyways, I need help and I'm very stuck. Send help!
