Struggling with creating and using functions python code challenge

The instructions are: Let's create a function that determines if a specific value is odd. Let's name the function is_odd and have it declare a single parameter. It should return True if the value is not divisible by 2. This is my code so far:

def is_odd(number):
    if number % 2 == 0

I can't figure out what the return should read. I've looked at the hints but they aren't clicking. Any help?

Hey Lauren` Welch, without giving he whole answer away, you can structure true/false return values i two ways:

  1. Using an if statement (like you have done), decide which value needs to be returned, the use either:
    return True
# or 
    return False
  1. If you can conveniently state the true/false decision in a single phrase, you can return the result redirectly:
# if you want true for a phrase that evaluates true use
    return <statement_evaluates_true>
# if you want false for a phrase that evaluates true use
    return not <statement_evaluates_true>

So say you want True if age grater than 21, use either:

def old_enough():
    if age > 21:
        return True
# or, use
def old_enough():
    return age > 21

Post back if you have more questions good luck

Thank you Chris! I changed my code from 

def is_odd(number):
    if number % 2 == 0:
        return False

When running 1 through the code it was returning false so I changed it to this

def is_odd(number):
    if number % 2 != 0:
        return True
