help me on this task

Alright, here's a fun task! 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.

here is my code

def combiner(mylist): number = 0 string = ""

for item in mylist:
    if isinstance(item, str):
        string += item

    elif isinstance(item, (int, float)):
        number += item

    return string + str(number)
instances.py 
def combiner(mylist):
    number = 0
    string = ""

    for item in mylist:
        if isinstance(item, str):
            string += item

        elif isinstance(item, (int, float)):
            number += item

        return string + str(number)

You are very close! The return is indented too far. This causes the for loop to return after the first iteration.
