Python Everything Website

Python Everything is a small blog I made to discuss and showcase anything related to Python and content about Raspberry Pi, Arduino, and useful Python modules. I developed it with Flask and MySQL. In order to mitigate the cost of hosting, the Flask application is converted to a static site and hosted on GitHub. The CI/CD is done with GitHub Actions.
