Not sure what I did wrong

The only error message I get is "Bummer: Try again!", but I don't know why my code wouldn't work.

instances.py 
def combiner(list):
    finalStr
    finalNum
    for item in list:
        if isinstance(item, (int, float)):
            finalNum += item
        else if isinstance(item, str):
            finalStr += item
    return finalStr + finalNum

UPDATE:

my code works when I remove the "else" that wasn't needed.

In Python we use three keywords for if statements. They are:

  • if
  • elif
  • else

if is used first, then elif is used. You can have as many elif's as you want in an if statement.

For Example:

x = 4
if x == 1:
    print("")
elif x == 2:
    print("")
elif x == 3:
    print("")
elif x == 4:
    print("")
else:
    print("")

Don't forget elif and else is optional!

So you code would look like this

def combiner(list):
    finalStr = ""
    finalNum = 0
    for item in list:
        if isinstance(item, (int, float)):
            finalNum += item
        elif isinstance(item, str):
            finalStr += item
    return finalStr + str(finalNum)

Other changes:

  • Initialized the variables
  • Converted finalNum to a string for the return
