On the output screen, Name is Deepak, Age is 12 and Grade is VII will be printed.

                  You must follow the given rules while creating and naming the variables:
                      A variable name must start with a letter or underscore character.
                      A variable name cannot start with a number.

                       A variable name can only contain alphanumeric characters (all the letters of the alphabet and
                      numbers) and underscores (_).
                      Variable names are case-sensitive.
                       Variable names cannot contain any special character or symbol.

                       A keyword cannot be used as a variable name.

                      DATA TYPES
                  A data type specifies the type of value a variable can contains. 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
                       float: Any real number in which a fraction is denoted by a decimal symbol. Example: a = 3.5

                       string: A string value is a collection of one or more characters put 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  # 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.
