Tell us what’s happening:

how to input some values into my code so that I can monitor my progress

Your code so far

def arithmetic_arranger(problems, show_answers=False):

    if len(problems) > 5:
        return 'Error: Too many problems.'

    for problem in problems:
        prob = problems.split()

        if prob[1] == '*' or prob[1] == '/':
            return "Error: Operator must be '+' or '-'."

        if prob[0].isdigit() or prob[2].isdigit() == False:
            return"Error: Numbers must only contain digits."

        if (prob[0]) or len(prob[2]) > 4:
            return "Error: Numbers cannot be more than four digits."
    else: 
        if prob[1] == '+':
            answer = prob[0] + prob[2]
        else:
            if len(prob[2]) > len(prob[0]):
                answer = prob[2] - prob[0]
            else:
                answer = prob[0] - prob[2]

You can see some example function calls in the tests below the instructions.

Make sure to pass the function call to print() and make sure your function returns something.

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

You can also use print() within your function to check on any variables or outputs

Am I doing it right? or is there something wrong with my code?

4

add a function call in your editor, like arithmetic_arranger(["3801 - 2", "123 + 49"]), so you can see the error

do I add it out of the function?

6

when you call a function, you write the function call outside the function, yes
