Tell us what’s happening:

the code runs perfectly I don’t understand why it dosen’t pass the test can someone help ?

Your code so far


def arithmetic_arranger(problems, show_answers = False):
    list_of_problemes = problems
    numbers = []
    operators = []
    upper_row = []
    middel_row = []
    hashes = []
    results = []
    for problem in list_of_problemes:
        if len(list_of_problemes) > 5 :
            return print('Error: Too many problems.')
        else:
            array = problem.split()
            numbers.append(array[0])
            numbers.append(array[2])
            operators.append(array[1])

        for number in numbers:
            if len(number) > 4:
                return print('Error: Numbers cannot be more than four digits.')
            elif not number.isdigit():
                return print('Error: Numbers must only contain digits.')
            
        for op in operators:
            if not op in ['+', '-']:
                return print("Error: Operator must be '+' or '-'.")
            
    for i in range(0, len(numbers), 2):
        num1 = int(numbers[i])          
        num2 = int(numbers[i + 1]) 

        hashes.append('-' * (max((len(numbers[i]), len(numbers[i + 1]))) + 2) )
        lenth = len(hashes[i // 2])

        upper_row.append(numbers[i].rjust(lenth, ' '))
        x = operators[i // 2] + numbers[i + 1].rjust(lenth-1, ' ')
        middel_row.append(x)

        if show_answers == True:
            if operators[i // 2] == '+':
                result = num1 + num2

        else:
            result = ''
        results.append(str(result).rjust(lenth,' '))

    upper_row = "    ".join(upper_row)
    middel_row = "    ".join(middel_row)
    hashes = "    ".join(hashes)
    results = "    ".join(results)

    return print(f'{upper_row} \n{middel_row} \n{hashes} \n{results}')

Return a string, not a print() call

If you want to print the result call the function like this:

print(arithmetic_arranger(["32 - 698", "1 - 3801", "45 + 43", "123 + 49", "988 + 40"], True))
