Ari Lamstein: Free Course: Learn to Build Data Apps with Streamlit!
I’m thrilled to launch a hands-on, week-long email course that walks you through building, customizing, and deploying an interactive data app in Python using Streamlit. By the end of seven short lessons, you’ll have a live app exploring US demographic data—and the confidence to tackle more complex projects on your own.
Below is an image of the final app you’ll build.
Whether you’re new to Streamlit or looking to sharpen your data app skills, this free course is designed to get you building fast—with real-world data and clear guidance.
How It Works
For seven days, you’ll receive a short email with:
- A step-by-step tutorial
- Self-guided exercises embedded right in the email
- Code snippets and screenshots to guide you
You’ll build the demo app locally, customize it, add new features, and deploy it with one click. If you get stuck, just hit “reply”—I’ll help you troubleshoot in real time.
