Tell us what’s happening:
Replit keeps saying theres a syntax error and i can’t figure out where. I though it was in the readme.md and I put a # there and the error went away. Now whenever I click run theres no output whatsoever

Your code so far

def arithmetic_arranger(problems, val=False):
    arranged_problems = ''
    if len(problems) > 5:
        arranged_problems = "Error: Too many problems."
        return arranged_problems

    # list of all operations in str format
    operations = list(map(lambda x: x.split()[1], problems))
    if set(operations) != {'+', '-'} and len(set(operations)) != 2:
        arranged_problems = "Error: Operator must be '+' or '-'."
        return arranged_problems

    numbers = []  # list of all operands in str format
    for i in problems:
        p = i.split()
        numbers.extend([p[0], p[2]])

    if not all(map(lambda x: x.isdigit(), numbers)):
        arranged_problems = "Error: Numbers must only contain digits."
        return arranged_problems

    if not all(map(lambda x: len(x) < 5, numbers)):
        arranged_problems = "Error: Numbers cannot be more than four digits."
        return arranged_problems

    top_row = ''
    dashes = ''
    values = list(map(lambda x: eval(x), problems))
    solutions = ''
    for i in range(0, len(numbers), 2):
        space_width = max(len(numbers[i]), len(numbers[i+1])) + 2
        top_row += numbers[i].rjust(space_width)
        dashes += '-' * space_width
        solutions += str(values[i // 2]).rjust(space_width)
        if i != len(numbers) - 2:
            top_row += ' ' * 4
            dashes += ' ' * 4
            solutions += ' ' * 4

    bottom_row = ''
    for i in range(1, len(numbers), 2):
        space_width = max(len(numbers[i - 1]), len(numbers[i])) + 1
        bottom_row += operations[i // 2]
        bottom_row += numbers[i].rjust(space_width)
        if i != len(numbers) - 1:
            bottom_row += ' ' * 4

    if val:
        arranged_problems = '\n'.join((top_row, bottom_row, dashes, solutions))
    else:
        arranged_problems = '\n'.join((top_row, bottom_row, dashes))
    return arranged_problems

What error says exactly? Could you link to your replit?

You should paste the Error as well here to make it more clear.

I’ve edited your code for readability. When you enter a code block into a forum post, please precede it with a separate line of three backticks and follow it with a separate line of three backticks to make it easier to read.

You can also use the “preformatted text” tool in the editor (</>) to add backticks around text.

See this post to find the backtick on your keyboard.
Note: Backticks (`) are not single quotes (').

Hi! Sorry for the late response. It says this:

It was missing the Pytest module in your Environment, I have Installed it through
pip install pytest command in the Shell to make the environment running. It is working fine now.
