Hey, so i’m having trouble passing the last 2 tests. Everything looks good in the preview but I see in the console that the spacing is off. I’ve tried playing with my code, but i can’t seem to fix it. Here is the console error: AssertionError: ’ [140 chars] m \n e \n n \n t’ != ’ [140 chars] m \n e \n n \n t ’
Your code so far

You might not be able to actually highlight your output this way in any case. The point being that you need spaces to square off the output after the last character

this is the part that i changed and now i’m getting ‘IndexError: string index out of range’
this is the part that i updated

Be sure and read more than just the first line of the failing message. The ability to read and comprehend error messages is a skill you’ll need to acquire as a developer. Ask questions on what you don’t understand.
The error message is pointing you to line 64. Look at what’s there and what could be the problem.
