On the output screen, a = 10 and b = 20 will be printed. You can also assign the same value
            to multiple variables at the same time in the following way:

            a = b = 20
            print (“a=”, a)
            print (“b=”, b)
            On the output screen, a = 20 and b = 20 will be printed.
            You can also assign multiple values to multiple variables in the same line in the following way:

            name, age, Class= ”Anaya”, 12, ‘VII’
            print (“Name is”, name)
            print (“Age is”, age)

            print (“Grade is”, Class)
            On the output screen, Name is Anaya, Age is 12, and Grade is VII will be printed in

            three lines.
            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.




                      DATA TYPES IN PYTHON

            A data type is used to define 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.
            Commonly used 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 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. Python does not execute comments.

            Comments are not a part of the program, but they do enhance the interactivity of the program
            and make them readable. Python supports two types of comments: Single-line-comments and
            multiline comments.

            Single-line Comment

            Python uses the hash (#) symbol for writing single-line comments.
