Add doc to Python section

[MichaelCurrin]

Add README. Follow pattern from Go section. Separate the folders and README description so there is a path for a developer. Add resources like https://www.codecademy.com/catalog/language/python and SoloLearn. Add cheat sheet section. As markdown or ipnb or scripts. Turn into a static site (scripts will be accessible so easily but could be pulled in). Or move to coding blog, if I want to make it more accessible and findable online than Github.
