Hey guys, been working on this for a couple days. Gives me the result I want in the console in PyCharm, doesn’t pass the replit test. Any help would be appreciated!

def arithmetic_arranger(problems, result=True):
final_first_line = ""
final_second_line = ""
final_barrier = ""
final_total = ""
if len(problems) > 5:
return "Error: Too many problems."
for problem in problems:
first_number = problem.split()[0]
second_number = problem.split()[2]
if not first_number.isdigit() or not second_number.isdigit():
return "Error: Numbers must only contain digits."
if len(first_number) > 4 or len(second_number) > 4:
return "Error: Numbers cannot be more than four digits."
operator = problem.split()[1]
if operator != "+" and operator != "-":
return "Error: Operator must be '+' or '-'."
total = eval(problem)
if max(len(first_number), len(second_number)) == 1 or max(len(first_number), len(second_number)) == 2:
barrier = "-" * 4
length = 4
elif max(len(first_number), len(second_number)) == 3:
barrier = "-" * 5
length = 5
elif max(len(first_number), len(second_number)) == 4:
barrier = "-" * 6
length = 6
display_total = str(total).rjust(length)
first_line = str(first_number).rjust(length)
second_line = str(operator.ljust(length - len(second_number)) + second_number).rjust(length)
final_first_line += f"{first_line} "
final_second_line += f"{second_line} "
final_barrier += f"{barrier} "
if result:
final_total += f"{display_total} "
arranged_problems = f"{final_first_line}\n" \
f"{final_second_line}\n" \
f"{final_barrier}\n" \
f"{final_total}\n"
return arranged_problems
print(arithmetic_arranger(["32 + 8", "1 - 3801", "9999 + 9999", "523 - 49"], True))

Edit: Jeez sorry about how messy this came out, haven’t used a forum with this kind of layout before

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

No errors in the console, this error repeatedly in replit;

E AssertionError: Expected different output when calling "arithmetic_arranger()" with ["3801 - 2", "123 + 49"]
E assert ' 3801 123 \n- 2 + 49 \n------ ----- \n\n' == ' 3801 123\n- 2 + 49\n------ -----'
E - 3801 123
E + 3801 123
E ? ++++
E - - 2 + 49
E + - 2 + 49
E ? ++++
E - ------ -----
E + ------ -----
E ? +++++
E +

If you see the series of pluses in the output, these indicate the presence of extra spaces.
These spaces are unexpected (and probably invisible to you in the console) but detected by the test.
You will need to remove them.

Hi, you could create a simple counter variable and increment it on each loop till you get to the final one.
There is probably more than one way to do this but I am curious about how the spaces are getting added and then stripped and yet still somehow end up in the final result. (I would try to log all that)

It seems the whitespace problem was sorted somewhere in my tinkering, now it’s just failing the initial 4 tests (display sums without totals) and passing the final 6 (error testing and sums displaying totals)

The error says you have one extra space at the end of the line of dashes. (See the plus sign pointing it out?)

Edit: it could also mean you have an extra hidden character there that is not a space (it just looks like a space to us but could be any hidden character like a newline)

I’m so stumped. Any hidden characters I remove make it completely wrong. Using strip and rstrip doesn’t seem to help. Should I not be using an f-string at all?

It’s a multi-line formatted string with the white space stripped at the end of each line. Works perfectly fine aesthetically, replit just doesn’t seem to like it.

Edit: Also genuinely confused how it works fine solving the problems with solutions, but doesn’t work without. It’s the exact same code.

I needed to adjust the dashes/whitespace. I also needed to ad an extra boolean condition only adding the final line if the condition was set to True. Thanks so much for your help!
