The program will execute and the output will be shown in the Shell window.

                        INPUT AND OUTPUT


                 Python provides two commonly used functions input() and print() for input and output.


                      The input() Function

                 The input() function takes the user’s input while a program executes. The general syntax of the input()
                 function is as follows:


                 input([<prompt>])
                 Here, prompt is the string or message we wish to display on the screen. Example:

                    name = input("Enter your name: ")
                   >>> Enter your name: "Mohan"

                      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.
