SPONSORBuilding a serverless hosting platformThe purpose of this project is to build a system that will allow us to push on a branch and deploy our changes in a separate environment, giving us a unique URL, to check them. Similarly to how now.sh and heroku.com are doing. We’ll need a mechanism that will package our code and dependencies and will deploy it, but also it needs to consider multiple versions, upgrades, load-balancing, scaling and our stateful part (database).Build & Deploy A Python Web App To Automate Twitter Learn how to build a tweet scheduler app using Flask, Heroku, the Twitter API & Google Sheets API.Teach kids Python by building an interactive gameOpen source tools can help anyone get started learning Python in an easy and fun way—making games.Build A Markdown To HTML Conversion Pipeline Using PythonWrite your posts in markdown and convert them into HTML using Python.Security scanners for Python and Docker: from code to dependenciesYou don’t want to deploy insecure code to production—but it’s easy for mistakes and vulnerabilities to slip through.
