                            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.

                                                        Using input() and print() functions

                                                                                            Introduction to Programming  131
