The example above is just there to help you remember how functions are structured.

Don't forget the colon at the end of your function definition!

Instructions

1. First, def a function called cubethat takes an argument called number. Don't forget the parentheses and the colon!
2. Make that function return the cube of that number (i.e. that number multiplied by itself and multiplied by itself once again).
3. Define a second function calledby_three that takes an argument callednumber.
4. if that number is divisible by 3,by_three should call cube(number) and return its result. Otherwise, by_threeshould return False.

Don't forget that if and elsestatements need a : at the end of that line!

def cube(number):
    number = number ** 3
    print number
    return number
    
def by_three(number)：
    if number % 3 == 0:
        return cube(number)
    else:
        print "2222"
        return False
        
number = input("number: ")
