Not passing in code challenge but terminal out is correct

Create a function named combiner that takes a single argument, which will be a list made up of strings and numbers. Return a single string that is a combination of all of the strings in the list and then the sum of all of the numbers. For example, with the input ["apple", 5.2, "dog", 8], combiner would return "appledog13.2". Be sure to use isinstance to solve this as I might try to trick you.

def combiner(arg):
    strlist = ''.join([x for x in arg if isinstance(x, str)])
    intlist = sum([x for x in arg if isinstance(x, int)])
    new_list = strlist+str(intlist)

    return new_list

Not all numbers are int.

In fact, the example given in the instructions includes a float value.

But you're really close. Just add "or isinstance(x, float)" to the conditional in your second comprehension and you should have it.
