TypeError: 'int' object not iterable

i don't see how i can solve this problem without looping through it

def combiner(list):
    for string, integer in list:
        if isinstance(string(str)) == True:
        if isinstance(integer(int,float)) == True:
            integer += integer
    return string + str(integer)

Hi Jason,

You do want to iterate through the list, but remember the proper syntax for for in loops. You choose one temporary variable name to represent the list element on each iteration:

for element in my_list:
    # do something with element

As such, you can't distinguish between the element types in the loop definition. Take another look at the syntax for isinstance to get an idea for how you can use your temporary variable to get the element's type.

You're also going to need to revisit the syntax for join().

Hope these point you in the right direction.

You wrote string(str), but string is not a function; it is a variable. You need to tell the program if your variable string is an instance of the class str, but you never told it what class you are checking it against.

Here is a link to the documentation on the function isinstance: https://python-reference.readthedocs.io/en/latest/docs/functions/isinstance.html

It also provides some examples that may help you out.
