Where do i go wrong ?

def combiner(*args): a = "" b = 0

for i in list(args):

    if isinstance(i,str):           
        a += i 
        print(a)
    elif isinstance(i,int) or isinstance(i,float):            
        print('{} i in int - '.format(i))
        b += i 
        print(b)



result = "{}{}".format(a, b)
return result

r = combiner("apple",5.8,"dog",8) print(r)

instances.py
def combiner(*args):
    a = ""
    b = 0


    for i in list(args):

        if isinstance(i,str):           
            a += i 
            print(a)
        elif isinstance(i,int) or isinstance(i,float):            
            print('{} i in int - '.format(i))
            b += i 
            print(b)



    result = "{}{}".format(a, b)
    return result

r = combiner("apple",5.8,"dog",8)

The instructions say the function will take "a single argument, which will be a list made up of strings and numbers".

Since there will only be one argument and it will already be a list, you don't need the "splat" (packing operator) in the definition (or the "list" function around the iterable).

I did try removing the split, still its throwing error. Though It gives me the answer when I try in the terminal.

Also, for the challenge you only need to define the function. You don't need to call it, create the variable "r", or "print" anything.
