Help with the Arithmetic Formatter project

[sage4104]

Hello! sorry for the repetitive subject and the bad English! but I couldn’t find help elsewhere , so I was done with the Arithmetic Formatter project, my code works well outside of the Freecodecamp console and even inside of it , yet it keep showing me error.

this is my code :

#!python3

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

	cond_1 = map(lambda x : x.split()[1], problems)
	if set(cond_1) != {'+', '-'}:
		return "Error: Operator must be '+' or '-'."

	cond_2 = map(lambda x : x.split(), problems)
	for item in cond_2:
		if(item[0].isdigit() and item[2].isdigit()) is False:
			return 'Error: Numbers must only contain digits.'
		if len(item[0]) > 4 or len(item[2]) > 4:
			return 'Error: Numbers cannot be more than four digits.'

	first = ''
	second = ''
	third = ''
	fourth = ''

	for problem in problems:
		width = max(len(problem.split()[0]), len(problem.split()[2]))
		first_Num = problem.split()[0].rjust(width+2)
		second_Num = f'{problem.split()[1]} {problem.split()[2].rjust(width)}'
		_dashes = '-' * (width +2)
		if problem.split()[1] == '+':
			result = str(int(problem.split()[0]) + int(problem.split()[2])).rjust(width+2)
		if problem.split()[1] == '-':
			result = str(int(problem.split()[0]) - int(problem.split()[2])).rjust(width+2)
		if problems != problems[-1]:
			first += first_Num + '    '
			second += second_Num + '    '
			third += _dashes + '    '
			fourth += result + '    '
		else:
			first += first_Num
			second += second_Num
			third += _dashes
			fourth += result

	if show_answers :
		res = first + '\n' + second + '\n' + third + '\n' + fourth
	else:
		res = first + '\n' + second + '\n' + third 
	return res

print(arithmetic_arranger(["32 + 8", "1 - 3801", "9999 + 9999", "523 - 49", "80 + 30"]))

this is result inside of Freecodecamp console :

this is the result outisde of freecodecamp :

this is the only error I get :

thank you in advance for all the tips!

[ILM]

please always post a link to the step/project/challenge when you ask for help. Can you do that now please?

---

have you looked at the browser console? it gives a more verbose test result

[sage4104]

yes sure! sorry about that! this is the link to the challenge :

freeCodeCamp.org

this is another photo from the Freecodecamp console the code seems to meet all the requirements

@ILM

have you looked at the browser console? it gives a more verbose test result

sorry here it is :

[ILM]

You seem to have overlooked this line

Note: open the browser console with F12 to see a more verbose output of the tests.

[sage4104]

[ILM]

If I run your code, I can see that, there is no need for a screenshot.

That is the full output of the tests, from there you can see the exact difference between your output and teh expected output

[sage4104]

yeah thanks for your help, the code I wrote outputs the problems outlined as the challenge require it to be.

[ILM]

no, it doesn’t, as you can infer from the test failing. There you can see the exact difference

[sage4104]

I still can’t see the problem since this is the output I get on the Freecodecamp console as well, if I try to tweak the spacing and stuff, it’s no longer aligned, thanks anyway I’ll keep trying.

[ILM]

this is from the screenshot you posted, it shows the difference between your code and the expected:

You have more characters than needed.

Also the assertion error.

AssertionError: '  1         1    \n+ 2    - 9380    \n---    ------    '
             != '  1         1\n+ 2    - 9380\n---    ------'

It’s all there for you to look at exactly for this reason.

[sage4104]

can you please hint out which lines of code I should modify ? I can’t find the error

[ILM]

which lines add four spaces?

[ILM]

@sage4104

if problems != problems[-1]:

you are comparing a list with a string

[sage4104]

damn, I did not pay attention to that one! added that ‘s’ by mistake , thank you a lott! now only one error left to fix

[sage4104]

thank you a lot ! it’s fixed now! I did not pay attention to “problems” and “problem” , the intension was to compare problem to problems[-1]

thank you a lot again
