Setting up Atom as a Python IDE [A How To Guide]

Setting up Atom as a Python IDE [A How To Guide] The guide shows how you can setup and maintain a python friendly development environment from within Atom. In a separate article I (will) show how to setup Microsoft Visual Studio Code in a similar manner. The guide is tested and valid for the latest version of Atom 1.40-40-Python 3. (It may work for earlier versions of Atom, but untested.) The guide includes a Linter Package (Source Code Checker) and a Script Package.
