Develop and sell a Machine Learning app -- from start to end tutorial

After developing and selling a Python API, I now want to expand the idea with a machine learning solution. So I decided to quickly write a COVID-19 prediction algorithm, deploy it, and make it sellable. If you want to see how I did it, check out the post for a step by step tutorial. In this article, I take the ideas from my previous article "How to sell a Python API from start to end" further and build a machine learning application. If the steps described here are too rough consider reading my previous article first.
