Comments are lines that start with a #. For example: # this is a comment! print "this is not a comment" # the previous line is not a comment, but the next line is: # print "this is not a comment" We can add comments to the code for ourselves or for someone else to read. Comments are used for: (1) adding a small description to the program, (2) explaining how a piece of code works if it is a bit cryptic, and (3) to'comment-out 'lines of code that should be (temporarily) ignored (see the last line of the example).
