# Arithmetic formatter fails but output is identical

Hey I can’t seem to get this right.
The output looks Identical to me when I do a == test its True. But and “is” is False. Sorry I really don’t know what I’ve done wrong.

def arithmetic_arranger(problems):
arranged_problems = str()
# pulling equation list
if len(problems) <= 2:
sums = problems[0]
else:
sums = problems
# Too many problem error
if len(sums) > 5:
print(“Error: Too many problems.”)
exit()

``````l1 = str()
l2 = str()
l3 = str()
l4 = str()
f = 0
for x in sums:

alen = 0

b = 0
blen = 0
c = 0

For a start your code will fail several tests because you are supposed to `return` error messages - not `print` them and call `exit()`.
Then it would be nice if you at least posted the errors you are getting, ideally even the link to your replit.

Okay thanks I’ll fix that but it’s not even getting past the second test.

Okay thanks I’ll fix it.
it would be:
arranged_problems = (“Error: Too many problems.”)
return arranged_problems

is that correct?
replit

Yes.
The other issues come from the fact you are not taking in a second argument in the function.

Thanks I passed. I really appreciate it.
