Arithmetic_arranger decoding the exact error

Sorry for the format of this Post

I am having trouble analyzing what is the exact problem.
I cannot decode the assertion error to understand where is the mismatch.
How to read this?

here is the code

this part shows you your lines starting with -, the expected lines starting with +, and the lines with ? point out the difference

in this case you have extra stuff at the end of the lines

Thank you… Now I see it…

Tell us what’s happening:
After correcting the last verification errors extra 4 spaces
The problem moved to

Your code so far

if not len(problems) < 5 :
    arranged_problems = "Error: Too many problems." 
    return "Error: Too many problems." 
  else :  
    for index, problem in enumerate(problems):

it works but it fails verification no matter how I implement the if statment

Love the comment about some Genius :slight_smile:

From the readme with the project : * If there are too many problems supplied to the function. The limit is five, anything more will return:
Error: Too many problems.

Currently, you have a maximum of 4 problems :wink:

Looking at the output, the 5th problem is causing the fail by not having added enough space in this problem or between the 4th and 5th. Maybe the Genius wanted all lines adjusted to the largest space needed for each problem?

well that is the problem it
it should not be worried about the format just the message “Error: Too many problems.”
re init all the variables
verified that the if statement works manually starting
started python
from arithmetic_arranger import arithmetic_arranger
arithmetic_arranger( [“11 + 4”, “3801 - 2999”, “1 + 2”, “123 + 49”, “1 - 9380”])
it works fine “Error: Too many problems.” is the return.
why is the verification failing

Fixed the 5 problems.
back to line 27 causing the fail

You tackled the most difficult part of the errors.
The assignment wants to be able to calculate a maximum of 5 problems, not 6 or more…(…line 17…_)

your line 27 did not cause an error when I ran the code?

got it … I been fiddling with the
if statement that I forgot to place it back to
len(problems) > 5

I hate it when that happens…

nice work, congrats!

Thank you very much for your help.
