• I'm right

import math

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

Some hints:

Convert a number in the string with str(n)

These "asserts" using only for self-checking and not necessary for auto-testing

if name == 'main': assert checkio(15) == "Fizz Buzz", "15 is divisible by 3 and 5" assert checkio(6) == "Fizz", "6 is divisible by 3" assert checkio(5) == "Buzz", "5 is divisible by 5" assert checkio(7) == "7", "7 is not divisible by 3 or 5"
