this code works in workspaces. Why doesn't it work for the challenge?

Hi, This code works in workspaces. Why doesn't it work for the challenge?

def combiner(items):

    # Hold values
    strings = ""
    nums = 0

    # Loop through list
    for item in items:

        # Test type of each element
        # If string, concatenate each to itself
        if isinstance(item, str):
            strings += item 

        # else if float or int, add together
        elif isinstance(item, (float, int)):
            nums += item
    print(strings + str(nums))

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

The challenge wants you to return the string. You are printing.

I was making the same mistake in a different challenge. Print and return are actually different statements (although they may sometimes have the same behavior). Print only displays an output to the user whereas return gives back a result to the function call. All functions return a value, even if there is no return statement (in which case the function will return None).
