How to program
Understand comments.
Comments are text which does not appear or affect the program in any way. These are used by programmers to leave notes or information for themselves or future programmers.
Generally, one or a series of characters will tell the computer that text is a comment and not part of the program, though what those characters are will depend on the programming language being used. For example, using the python language the hash or number sign indicates a comment.
