merging of strings and integers

I still don't understand why my code is wrong. I know that instead of else in if-else-statement, I could have used the following code to exclude boolean values:

elif isinstance(item, str): list_words.append(item)

But in the question is mentioned that the argument of the function will only consist of strings and numbers. That's why I've used the 'else statement'..

The code works just fine when I run in Atom, but somehow in workspace it doesn't do anything.

What am I doing wrong here?

def combiner(arg):
    list_numbers = []
    list_words = []

    for item in arg:
        if isinstance(item, (int, float)):

    sum_numbers = sum(list_numbers)
    merged_words = "".join(list_words)

    print(merged_words + str(sum_numbers))

You got this Sameer. It's just that the challenge insists on seeing a return statement instead of print.

Thank you for your response. It worked :)

Mark is right and with that change you will pass the challenge. But try the following:

combiner(["apple", 5.2, "dog", 8, "\n"])

combiner(["apple", 5.2, "dog", 8, "\", "n"])

combiner(["apple", 5.2, "dog", 8, "n", "\"])
