    The print() Function

                      The  print() function  prints or sends the output  to  the standard  output  device,  which is usually a
                      monitor. This function auto converts the items to strings, i.e., if you try printing a numeric value, the
                      print() function will automatically convert it into equivalent string and print it. The print() function
                      also introduces spaces between items automatically. The general syntax of the print() function is as
                      follows:

                        print [<expression 1> , <expression 2>...]
                      Example:

                        print ("Python is easy").
                      Let's create a program to use the input( ) and print( ) functions.

                                                          Using input() & print() functions

                             VARIABLES IN PYTHON

                      Variables are memory reference points where we store values which can be accessed or changed
                      later. The names given to the variables are known as identifiers. In Python, we do not need to specify
                      the type of variable because Python is a dynamically typed language and it identifies the variable type
                      automatically. Let’s understand this with the help of the given examples.

                        num = 0.4
                        _price = 30.3

                        TOTAL = round(_price * num,2)

                        print(TOTAL)

                           Declaring and Initializing a Variable

                      In Python, variables are declared and initialised at the same time in the following way:

                        a = 10

                        b = 20
                        print ("a=", a)

                        print ("b=", b)
