Arithmetic-formatter

Hello Everyone,

I am stuck with the project for 2 days as I cannot pass the test cases, my output is identical. Here’s my code,

def arithmetic_arranger(problems, solve=False):

  if (len(problems) > 5):
    return "Error: Too many problems."

  first = ""
  second = ""
  lines = ""
  sumf = ""
  string = ""

  for p in problems:
    firstNum = p.split(" ")[0]
    operator = p.split(" ")[1]
    secondNum = p.split(" ")[2]

    if (not firstNum.isnumeric() or not secondNum.isnumeric()):
      return "Error: Numbers must only contain digits."

    if len(firstNum) > 4 or len(secondNum) > 4:
      return "Error: Numbers cannot be more than four digits."

    if (operator == "/" or operator == "*"):
      return "Error: Operator must be '+' or '-'."

    sum = ""

    if operator == "+":
      sum = str(int(firstNum) + int(secondNum))

    elif operator == "-":
      sum = str(int(firstNum) - int(secondNum))

    length = max(len(firstNum), len(secondNum)) + 2

    top = str(firstNum).rjust(length)
    bottom = str(operator) + str(secondNum).rjust(length - 1)
    line = ""
    ans = str(sum).rjust(length)

    for l in range(length):
      line += "-"

    if p != p[-1]:
      first += top + '    '
      second += bottom + '    '
      lines += line + '    '
      sumf += ans + '    '

    else:
      first += top
      second += bottom
      lines += line
      sumf += ans

  if solve:
    string = first + "\n" + second + "\n" + lines + "\n" + sumf
  else:
    string = first + "\n" + second + "\n" + lines

  return string

this error is saying that you have an extra set of 4 spaces after each line that are unexpected.

hi Nathan, this is a certification project. You have to be careful how much help you give especially when no specific question has been asked. (otherwise it appears to be bordering on cheating)

Thank you, Yes my formatting conditional statement was the one with the issue as I needed to do p != problems[-1] instead of p != p[-1]. Thank you again for the help.

What do you mean by “import my project”? Normally people just click the replit reject link from the fCC page and it opens.
