Netflix OSS is a set of open source tools developed by Netflix.

Is there any interesting Python project worth your time? Maybe. Although according to the Pythonistas, Python is heavily used at Netflix, the open source libraries seem too specific to their use cases.

A monkey that monitors your AWS policies is definitely promising. A bot for GitHub organization management sounds fun.

Below are the top 5 python projects that I found most interesting.
