This is a new repository for Python for DevOps Lecture/Workshop

Scaffold

1. Create a Python Virtual Environment python3 -m venv ~/.venv or virtualenv ~/.venv
2. Create empty files: Makefile, requirements.txt, main.py, Dockerfile, mylib/__init__.py
3. Populate Makefile
4. Setup Continuous Integration, i.e. check code for issues like lint errors

5. Build cli using Python Fire library ./cli-fire.py --help to test logic

Containerized Continuous Delivery

Learn to build real-world Python Microservices that enable Continuous Delivery. This is a cool walkthrough because it is very similar to what someone would do at work building NLP Microservices on Amazon Web Services (AWS)
