I could be wrong, but doesn’t +None mean that you aren’t returning anything? I had similar where I had a print displaying the correct output, but i wasn’t returning the output so it failed the tests. But it could be something else.

You were right!

Hahaha look what happend, I had an indentation where it shouldn’t be, so the “return” statement weren’t running if the second argument of the function was “True”.

  if res==True:
    arranged_problems=linea1+"\n"+linea2+"\n"+linea3+"\n"+linea4
    print(arranged_problems)
  else:
    arranged_problems=linea1+"\n"+linea2+"\n"+linea3
    print(arranged_problems)

    return arranged_problems

Thank you!!
