latest Python 3.0 is a new version of the language that is incompatible with the 2.x line of releases. The language is mostly the same, but many details, especially how built-in objects like dictionaries and strings work, have changed considerably, and a lot of deprecated features which are avilable in earlier versions have finally been removed. Also, the standard library has been reorganized in a few prominent places of folder structure.
Python Command Line Basics
Before start installing Python, it’s important to have a very quick overview of how to work at the command line.
This allows you to programmatically move through your computer’s directories
