I'm having issue completing this part.

Is this normal that I'm having some serious trouble and is about to get some help? Or should I solve it myself to be good at this and practice myself?

```
Replace this line with your code.
def cube(number):
return number**number
def by_three(number):
if number % 3 == 0:
print "%d is divisible by 3" % (number)
else:
print "%d is not" % (number)
cube(6)
by_three(8)
```
