Hey. I know the answer for your question. I faced the same problem today and I have found a solution.
Pay special attention to the line 3 in your code. You have to use the method isalpha() with the "original" variable while using "print". (e.g. print original.isalpha(): )
In your case, as well as it was in mine - the "original" will be the input from user and it will be outputted exactly like it was inputted till the moment you change conditions.
As I understood, Codecademy automated tests just compare your output with expected result. So it prints exactly what you've written at print part of your code.
Hope, I was helpful.
