    Libraries and Tools: Programming in Python is easier because the libraries and supporting
                        tools make even a complicated task easy.

                         Interpreted: The interpreted language allows for easy debugging as it executes code line by line.
                         Integrated and Extensible language: We can easily integrate Python with other languages
                        such as C, C++. We can also write and compile a Python code in C or C++.

                         Dynamic Memory Allocation: When an object is created in Python, memory is dynamically
                        allocated to it. This memory is also retracted when it is no longer being used.

                         Object-Oriented: Python has an object-oriented approach. This means that the programs are
                        designed using objects and classes that interact with each other.

                                PROGRAMMING MODES IN PYTHON

                      Python provides two basic programming modes: Interactive Mode and Script Mode.

                      INTERACTIVE MODE (IDLE SHELL WINDOW)

                      The IDLE Shell window is an interactive window where we can type a Python code and view the
                      output in the same window. In the IDLE Shell window, the >>> sign appears. Here, we can type our
                      code and get output by pressing the Enter key.

                                   Short key  To close IDLE window:             Subject: To exit IDLE window

                                                                                To exit  the  IDLE window, click  on
                                         Ctrl +
                                                     D
                                                                                            Exit option.
                                                                                File menu

                      SCRIPT MODE (EDITOR’S WINDOW)
                      Python Shell executes commands immediately and doesn't save them for later use. For multi-
                      line code and to save your work for future use, you should use Python script mode. This allows
                      you to write larger programs and run the same code multiple times. Save your code in a file, for
                      example, 'filename.py' and run it to see all the output after execution. To open Python Editor’s
                      Window: click on the File menu    click on the New File option.
