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)
print(r)
```

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.
