These are the instructions

First, def a function called cube that takes an argument called number. Don't forget the parentheses and the colon!

Make that function return the cube of that number (i.e. that number multiplied by itself and multiplied by itself once again).

Define a second function called by_three that takes an argument called number.

if that number is divisible by 3, by_three should call cube(number) and return its result. Otherwise, by_three should return False.

I did

def cube(number):

return number*number*number

def by_three(number)

if n % 3 == 0:

return cube(number)

else:

return False

Where am I going wrong?
