My combiner function isn't running. Any suggestions?
def combiner(listsn):
total = 0
words = ""
for sn in listsn:
if isinstance(sn, (int, float)):
total += sn
else if isinstance(sn, str):
words += sn
total = str(total)
words = words.join(words)
words = words.join(total)
return words

Treehouse Moderator 68,457 PointsYou are close! A few errors to correct:
- "else if" should be
elif
- joining the
words
list should be
words = "".join(words)
-
return
statement should be indented less to align with thefor
statement - since
words
andtotal
are finally both strings, they can be returned simply as
words + total
Post back if you need more help. Good luck!!!
