Running a Python Program
                Follow these steps to run a Python program:

                Step 1:    Click on Run in the Menu bar.
                Step 2:    Click on Run Module option.
                                                                                                   Running a program
                The program will execute and the output will be shown in the Shell window.

                                                                                     Inf     Byte

                                                                                       Interactive  Mode  is
                                                                                       very useful  for testing
                                                                                       a code as it displays
                                                                                       the errors one by one.

                                                Output

                        Input and Output

                Python provides two commonly used functions input() and output() 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>...]
                For example:
                print ("Python is easy").

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