              DATA TYPES

              A data type specifies the type of value a variable can contain. For example, a person’s name must be
              stored as a string value, whereas the person’s age must be stored as an integer.
              Data types in Python are:
                   int: Positive or negative whole numbers (without any fractions). Example: a = 3, b= -5

                   float: Any positive or negative real number in which a fraction is denoted by a decimal number.
                 Example: a = 3.5
                   string: A string value is a collection of one or more characters enclosed in single or double quotes.
                 Example: a="hello"
              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 the # 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 comments and multiline comments.

              Single-line Comment

              In case a user wants to specify a single-line comment, then the 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 dedicated syntax for multiline comments. To add a multiple-line comment, you
              could insert a # for each line. Example:
                      Program :                                    Output :

                      #printing a string                           Rakesh
                      #print two names                             Rachna
                      print("Rakesh")
                      print("Rachna")

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

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