COMMENTS IN PYTHON


                 Comments in Python can be used to explain parts of the code. It can also be used to hide the code as
                 well. Comments enable us to understand the way a program works. In Python, any statement starting
                 with # symbol is known as a comment. Python does not execute comments. Comments are not a part
                 of the program, but they do enhance the interactivity of the program and make it readable. Python
                 supports two types of comments: Single line comment and Multiline comment.


                      Single Line Comment

                 In case, a user wants to specify a single line comment, then comment must start with the symbol #.
                 Example:
                   Program:                                         Output:

                   # printing a string                              Hello World
                   print("Hello world")


                      Multiple-line Comment


                 Python does not have a syntax for multiline comments. To add a multiple-line comment, you could
                 insert a # for each line.
                 Example:

                       Program :                                    Output :
                       # printing a string                          Hello World
                       #print five names                            Rachna
                                                                    Sambhav
                       print("Hello World")
                                                                    Akshat
                       print("Rachna")
                                                                    Tushar
                       print("Sambhav")
                       print("Akshat")

                       print("Tushar")

                 However, the text written inside triple quotes (''' or ''"") is also considered as comment. You can use
                 the triple quotes to write multiline comments. For example:

                                  '''This is                         """This is
                                     Multiline              OR          Multiline

                                     Comment'''                         Comment"""


                        OPERATORS

                 In Python,  operators can  be  defined  as  special  symbols  which perform arithmetic  and  logical
                 computation. The values which the operators use to get the output are called operands. For example,
                 in the expression 10 – 5, 10 and 5 are operands and the minus (–) sign is the operator.
