I'm stuck in arithmetic formatter :(

Python

I try anyway i can to do this. But it doesn’t work

def arithmetic_arranger(*problems):
    count = 0;
  
    tops = ""
    bottoms = ""
    operators = ""
    sums = ""
    for problem in problems[0]:
        #print(problem)
        count += 1

        #print("count  " + str(count))
        if(count > 5): return "Error: Too many problems."
        cutProblems = problem.split()
        #print(math.isnan (float(cutProblems[0])))
        if (cutProblems[0].isnumeric() and cutProblems[2].isnumeric()):
            a = cutProblems[0]
            b = cutProblems[2]
            op = cutProblems[1]
            if( int(a) >= 10000 or int(b) >= 10000): return "Error: Numbers cannot be more than four digits."
            if op == "+" or op == "-": 
                #x.append(a + b)
                if op == "+": final = int(a) + int(b)
                elif op == "-": final = int(a) - int(b) 
                length = max(len(a), len(b)) + 2
                top = a.rjust(length)
                bottom = op + b.rjust(length - 1)
                
                operator = ""
                operator = operator.rjust(length, "-")
                sum = str(final).rjust(length)

                tops += top + "    "
                bottoms += bottom + "    "
                operators += operator + "    "
                sums += sum + "    "
            else: return "Error: Operator must be '+' or '-'."
        else: return "Error: Numbers must only contain digits."
    tops.rstrip()
    bottoms.rstrip()
    operators.rstrip()
    sums.rstrip()
    if(len(problems) > 1 and problems[1] == True):
        arithmetic_problems = tops + "\n" + bottoms + "\n" + operators + "\n" + sums
    else: arithmetic_problems = tops + "\n" + bottoms + "\n" + operators + "\n" 
    return arithmetic_problems

and this is result

Hello there.

Do you have a question?

If so, please edit your post to include it.

this is showing that there is a difference between your output and the expected one at the end of each line

This is false. The code is largely correct.
