IndexError: list index out of range | Snake game

I'm learning Python and that is why I'm programming the snake game. I'm supposed to want to place a map within the play area. I input the map in String form and then break it to form rowed lists. The problem is that I get the error Index Error: list index out of range. Somebody could help me?

You should learn how to debug your code. You are missing the spaces in your snake map on the 6th row.
