You can also install  the  Python  IDLE  (Integrated  Development  and  Learning  Environment)
                  separately. It is a code editor which helps you to write and execute Python programs in the editor
                  itself. Follow the below steps to install Python IDLE:

                  Step 1      Open the Terminal and type the following command:
                            $ sudo apt-get install idle-python3.8
                  Step 2    Press the Enter key. When you press the Enter key, Terminal will ask you to enter the
                            password.

                      PROGRAMMING IN PYTHON

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

                  Interactive Mode is a command line shell which gives immediate result for each command. In
                  Interactive mode, you 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 Show Applications button.

                  Step 2    Type idle in the Search box.
                  Step 3   Click  on  IDLE  (using Python).  The  Python  IDLE
                            window opens in the Interactive mode.

                  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.
                      ✶  Prompt: You will see a blinking cursor after the symbol (>>>) in the window. This is known
                        as the Prompt. The Prompt allows the user to enter commands directly into Python and

                        get an output instantly by pressing the Enter key.
