i don't understand why this wont pass.

This took me three days to get this to work, but still not passing on the actually test, and i don't know why. i've tried different inputs, and i'm always getting back string seperated with nothing, then sum of my number list.....please help.

instances.py 
def combiner(items) :
    string = []    
    number = []
    s = ""
    for item in items:
        if isinstance(item, str) == True:
            string.append(item)
        elif isinstance(item, int) == True:
            number.append(item)  
    string = s.join(string)
    combined = f"{string}{sum(number)}"
    return combined

You also need to consider floats

def combiner(items) : string = []
number = [] s = "" for item in items: if isinstance(item, str) == True: string.append(item) elif isinstance(item, (int, float)) == True: number.append(item)
string = s.join(string) combined = f"{string}{sum(number)}" return combined

fixed it about 2 seconds ago. was trying to update. lol

Thanks, that answer was spot on thought. Ended up testing with a float. notice it was getting out throw out cause of elif. researched how to add to arg in to isinstance, then bing bang boom!!
