• first python ever

 
def checkio(number):
    if number%3==0 and number%5==0:
        number = "Fizz Buzz"
    elif number%3==0:
        number = "Fizz"
    elif number%5==0:
        number = "Buzz"
    else number%3!==0 and number%5!==0:
        return str(number)

tried many variations, anyone know how to fix what I'm doing wrong?
