Please explain why I'm getting an error (Bummer) when submitting code. The function is returning string as expected.

The combiner function is returning string as expected.

instances.py 
combo = ["apple", 5.2, 8, "dog"]
numberlist = []
stringlist = []
def combiner(item):

    for x in combo:
        if isinstance(x, str):
            stringlist.append(x)
        else:
            numberlist.append(x)

    num1 = sum(numberlist)
    str2 = "".join(stringlist)

    str3 = str2 + str(num1)
    return str3

result = combiner(combo)
print(result)

Your parameter is item so you should iterate with that. 

for x in item:

Currently your function only returns the results for list combo so if the checker were to submit for example

result = combiner(["test", 1, 2, 3])

the result would still be appledog13.2

Thank you Kris for your feedback. It worked.

combo = ["apple", 5.2, 8, "dog"]

def combiner(item): numberlist = [] stringlist = [] for x in item: if isinstance(x, str): stringlist.append(x) else: numberlist.append(x)

return "".join(stringlist) + str(sum(numberlist))

combiner(combo)
