Challenge instances.py could not be accepted

I've written this code. It works under PyCharm. I cannot figure out where is the mistake.

def combiner(*args): argstr = '' argnum = 0.0 for item in args: if isinstance(item, str): argstr = argstr + item else: argnum = argnum + float(str(item)) print(argstr + str(argnum)) return (argstr + str(argnum))

combiner("apple", 5.2, "dog", 8)

instances.py 
def combiner(*args):
    argstr = ''
    argnum = 0.0
    for item in args:
        if isinstance(item, str):
            argstr = argstr + item
        else:
            argnum = argnum + float(str(item))
    return (argstr + str(argnum))

The instructions say that the function "takes a single argument, which will be a list..."

So since there will only be one argument, you won't need a "splat" operator to gather several individual ones.

Otherwise, good job. :+1:

Good news, but I didn't really do anything!
