Tell us what’s happening:

So my code passes all the tests, but is not getting any answer right (for some reason). Can someone explain why

Your code so far

def arithmetic_arranger(problems, show_answers=False):
    first_line = []
    second_line = []
    dashes = []
    results = []
    for prob in problems:
        num1, operator, num2 = prob.split()
        if len(problems) > 5:
            return print('Error: Too many problems.')
        elif "x" in prob or "X" in prob or "/" in prob or "%" in prob:
            return print("Error: Operator must be '+' or '-'.")
        elif num1.isdigit() == False or num2.isdigit() == False:
            return print('Error: Numbers must only contain digits.')
        elif max(len(str(num1)), len(str(num2))) > 4:
            return print('Error: Numbers cannot be more than four digits.')
        else:
            spacelines = "-" * (max(len(str(num1)), len(str(num2))) + 2)
            spacenum1 = " " * (len(spacelines) - len(num1))
            spacenum2 = " " * (max(len(str(num1)), len(str(num2))) - len(num2))
            spaceres = " " * (len(spacelines) - (max(len(str(num1)), len(str(num2)), len(str(int(num1) + int(num2))))))
            spaceresn = " " * (len(spaceres)-1)
            num1 = int(num1)
            num2 = int(num2)

            first_line.append(f"{spacenum1}{num1}")
            second_line.append(f"{operator} {spacenum2}{num2}")
            dashes.append(spacelines)
            if show_answers:
                result = num1 + num2 if operator == '+' else num1 - num2
                if result > 0:
                    results.append(f"{spaceres}{result}")
                else:
                    results.append(f"{spaceresn}{result}")

    print("    ".join(first_line))
    print("    ".join(second_line))
    print("    ".join(dashes))
    if show_answers:
        print("    ".join(results))

arithmetic_arranger(["3801 - 2", "123 + 49"])

Your function needs to return a string, not print it.
