In programming we use comments for –
- Making our code more informative or illustrative to third person.
- Making our code easy to understand and interpret.
- Preventing some code lines to from execution.
Single Line Comments
We simply use Hashtag(#) in the beginning of a line to make it a single line comment, as mentioned below

Practical demonstration of how we can prevent a line in a code from execution by using comments is mentioned below. Hello string is not printed in output as we made that line a comment.

Multiline Comment
We can simple use Hashtag(#) before as many lines as we want to make multiline commenting as demonstrated below

Or we could use other way for multiline comments which is triple double or single quotes.
