Whats wrong with my code

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.

def combiner(list1):
num = 0
string = ""

    for item in list1:
        if isinstance(item, str):
            string += item

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

        return string + str(num)

Hi Norman,

The problem is indentation! Python is really particular about indentation. Here's how it should look:

def functionname():  # indented 0
    variable  # indented 1
    variable  # indented 1

    for item in list:  # indented 1
        do_stuff  # indented 2
    return value  # indented 1

Fix your indentation, and the rest of your function looks good!

Cheers :beers:
