This is a free, week-long email course designed to teach participants how to build an interactive data app using Python and Streamlit. Over seven short lessons, users will learn to create, customize, and deploy a live app that explores US demographic data. The course provides step-by-step tutorials, self-guided exercises, and code snippets in each daily email. Participants will build the app locally, modify it, add features, and deploy it with a single click. Real-time troubleshooting support is available by replying to the emails. The curriculum progresses from introducing Streamlit to setting up a local app, making edits, modifying the app, and finally deploying it. By the end of the course, participants will have a functional Streamlit app and the knowledge to tackle more advanced projects. The course aims to get users building quickly with real-world data and clear instruction. It concludes by preparing learners for more complex applications and future projects.
