My output looks like the example they gave me and it still doesn't work

[RSilva9]

I’m doing the Build an arithmetic formatter project and my code (even though I know it can surely be done in a simpler way) is not working with what it asks me to do, despite the output being correct.

def arithmetic_arranger(problems, show_answers=False):
    if len(problems) > 5:
        return "Error: Too many problems."
    for prob in problems:
        if prob.find("+") == -1 and prob.find("-") == -1:
            return "Error: Operator must be '+' or '-'."

        split_prob = prob.split(" ")
        if not split_prob[0].isnumeric() or not split_prob[2].isnumeric():
            return "Error: Numbers must only contain digits."

        if len(split_prob[0]) > 4 or len(split_prob[2]) > 4:
            return "Error: Numbers cannot be more than four digits."

    results = []
    no_results = []
    for prob in problems:
        split_prob = prob.split(" ")
        longest_operand = 0
        longest_operand = max(len(split_prob[0]), len(split_prob[2]))
        if split_prob[1] == '+':
            result = int(split_prob[0]) + int(split_prob[2])
        else:
            result = int(split_prob[0]) - int(split_prob[2])
        block_with_result = f"{split_prob[0].rjust(longest_operand+2)}\n{split_prob[1]}{split_prob[2].rjust(longest_operand+1)}\n{'-'*((longest_operand)+2)}\n{str(result).rjust(longest_operand+2)}"
        results.append(block_with_result)

        block_without_result = f"{split_prob[0].rjust(longest_operand+2)}\n{split_prob[1]}{split_prob[2].rjust(longest_operand+1)}\n{'-'*((longest_operand)+2)}"
        no_results.append(block_without_result)
    
    lines = ["", "", "", ""]

    if show_answers:
        for block in results:
            split_block = block.split("\n")
            ran = len(split_block)
            for i in range(ran):
                lines[i] += split_block[i] + "    "

        final_output = "\n".join(lines)
        return final_output
    else:
        for block in no_results:
            split_block = block.split("\n")
            ran = len(split_block)
            for i in range(ran):
                lines[i] += split_block[i] + "    "

        final_output = "\n".join(lines)
        return final_output

# print(f'\n{arithmetic_arranger(["32 + 698", "3801 - 2", "45 + 43", "123 + 49", "112 * 5"])}')
