    Running a Python Program

                     Follow these steps to run a Python program:

                      1   Click  on  Run  in                                        2
                          the Menu bar.              Click on Run Module option.                             Hintbot

                                                                                                     Shortcut to run a
                                                                                                     Python program:
                                                                                                       Press F5 key

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

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

                          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
                     By default, Python considers the input as string even if you entered a number as input. You cannot
                     perform calculations on string. To perform calculations, you need to convert the string into integer or
                     floating-point value. To do so, Python provides following functions:
                         int(): It is used to change the input data value into integer. For example,

                        a = int(input("Enter a number "))

                     Now, the valid value entered is converted into integer value.
                         float(): It is used to change the input value into floating-point value. For example,

                        a = float(input("Enter a number "))

                     Now, the valid value entered is converted into floating-point value.

                                                                                                              #Python 141
