Tell us what’s happening:

I was doing the first certification project and everything was doing well. I started testing everything that the project requires and all worked as expected but when I run the tests to aprove the project the test number 5 where when putting more than 5 problems it should return “Error: Too many problems” isn’t checked but after I tested it by myself, worked well. What should I do?

Your code so far

def arithmetic_arranger(problems, show_answers=False):
    # Check the number of problems
    if len(problems)>5:
        return('Error: Too many problems')

    first_line=[]
    second_line=[]
    dashes = []
    answers = []

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

        # Check if the operator is valid
        if parts[1] not in ['+', '-']:
            return "Error: Operator must be '+' or '-'."
        
        # Check if operands are digits
        if not parts[0].isdigit() or not parts[2].isdigit():
            return "Error: Numbers must only contain digits."
        
        # Check if operands are at most four digits
        if len(parts[0]) > 4 or len(parts[2]) > 4:
            return "Error: Numbers cannot be more than four digits."
        
        # Calculate the width of the problem
        width = max(len(parts[0]), len(parts[2])) + 2

        # Format each part
        first_line.append(parts[0].rjust(width))
        second_line.append(parts[1] + " " + parts[2].rjust(width - 2))
        dashes.append('-' * width)

        # Calculate the answer if required
        if show_answers:
            if parts[1] == '+':
                result = str(int(parts[0]) + int(parts[2]))
            else:  # subtraction
                result = str(int(parts[0]) - int(parts[2]))
            answers.append(result.rjust(width))

     # Join each line with four spaces between problems
    arranged_problems = (
        "    ".join(first_line) + "\n" +
        "    ".join(second_line) + "\n" +
        "    ".join(dashes)
    )
    
    # Add answers if show_answers is True
    if show_answers:
        arranged_problems += "\n" + "    ".join(answers)
    
    return arranged_problems

# Test 1
print(f'\n{arithmetic_arranger(["3801 - 2", "123 + 49"])}')

# Test 2

# Test 4

# Test 9
print(f'\n{arithmetic_arranger(["3 + 855", "988 + 40"], True)}')

# Test 10
print(f'\n{arithmetic_arranger(["32 - 698", "1 - 3801", "45 + 43", "123 + 49", "988 + 40"], True)}')

You did not check the browser console as suggested, didn’t you?

AssertionError: 'Error: Too many problems' != 'Error: Too many problems.'
- Error: Too many problems
+ Error: Too many problems.
?                         +

Thank you, I didn’t check it and I couldn’t find what was the problem. Have a nice day!
