What You Need!
                        Install Python from its official website.
                        It comes with its IDLE code editor.
                    
You can also use Notepad++ or Microsoft's Visual Basic to edit python codes.
Using Python's IDLE
To create a new file: click File, New File.
                        To run python codes from the IDLE editor:
                        click Run, Run Module; or F5
                        
                        You can also run python codes from a command shell;
 open a command shell
                        and type python filename.py.
                        
                        (To edit an existing python file in IDLE, right-click on the file and select
                        Edit with IDLE).
                    
                        Notice: Our colour coding follows that of Python's IDLE.
                        Python's IDLE has no auto-completion for braces and quotes though, 
                        so feel free to use Notepad++.
                        (To turn auto-completion on in Notepad++, click on 
                        Settings >> Preferences >> Auto-Completion.)
