Build an Arithmetic Formatter Project

I have completed the code but all my results are not matching… can anyone tell me what is the mistake in my code?

def arithmetic_arranger(digits, show_results=False):
    # Making arrangement
    first_line = []
    second_line = []
    dashes = []
    results = []

    if len(digits) > 4:
        return 'Error: Too many problems.'

    for digit in digits:
        # Split digits
        parts = digit.split()
        num1 = parts[0]
        operator = parts[1]
        num2 = parts[2]

        # Valid input situations
        if operator not in ['+', '-']:
            return "Error: Operator must be '+' or '-'."
        if not (num1.isdigit() and num2.isdigit()):
            return 'Error: Numbers must only contain digits.'
        if len(num1) > 4 or len(num2) > 4:
            return 'Error: Numbers cannot be more than four digits.'

        # Deciding width
        width = max(len(num1), len(num2)) + 2

        # Shaping digits in a format
        first_line.append(num1.rjust(width))
        second_line.append(operator + ' ' + num2.rjust(width - 2))
        dashes.append('-' * width)

        # Result display
        if show_results:
            if operator == '+':
                result = str(int(num1) + int(num2))
            else:
                result = str(int(num1) - int(num2))
            results.append(result.rjust(width))
    # Combine the lines into a single output
    arranged_digits ='\n' + '    '.join(first_line) +'\n' +'    '.join(second_line) + '\n' +'    '.join(dashes)

    if show_results:
        arranged_digits +='\n' +'    '.join(results)
    return arranged_digits

# Test the function
print(arithmetic_arranger(["32 + 8", "1 - 3801", "9999 + 9999", "523 - 49"], True))

my output

look at the browser console like isntructed in the last line of the isntructions

the operations number to handle, you may need to check it again
