COMMENTING IN YOUR REAL PROGRAM

Commenting in your program is really a good habit.
because you may forget why a particular part of the code was written.
It also helps other programmer to easily understand and edit in program.

# THIS IS A COMMENT LINE
#THIS IS A SINGLE LINE COMMENT
'#' skips all the words written in that particular line.

A MULTILINE
