Good Morning.

I've been stuck in this lesson for an hour and so far I have not been able to figure out what it is you have to do.

```
def cube(number):
return number**number
def by_three(number):
if cube(number) / 3 :
return cumber(number)
else:
return "False"
by_three(number);
```

**Error message: Oops, try again. Did you create a function called "by_three"?**
