Dynamically typed language: Python is a dynamically typed language. This means that

                      you do not need to declare the type of variables in advance. For example, if you write a = 15,
                      you do not need to specify the variable a as an integer or string.

                      PROGRAMMING IN PYTHON

                  Python has two basic programming modes— Interactive Mode and Script Mode.

                  Interactive Mode


                  Interactive  Mode is a command line shell which  gives immediate
                  result for each command. In Interactive mode,  we type one command
                  at a time. Python executes the given command and gives the output.

                  Follow these steps to start Python and work in Interactive Mode:
                  Step 1:    Click on Start button.

                  Step 2:      Scroll down the list of programs and click on Python 2.7.9
                             folder.                                                               Opening Python

                  Step 3:    Click on IDLE (Python GUI).
                  The main IDLE window appears. IDLE stands for Integrated Development and Learning
                  Environment. It is a code editor which helps you to write and execute Python programs in

                  the editor itself.
                  Components of Python IDLE Window

                  There are two components of Python IDLE window:

                       Menu Bar: The Menu Bar of Python IDLE window is similar to the Menu Bar of other programs.
                      It has various menus such as File, Edit, Shell, Debug, Options, Window and Help.
