Read the storyLearn about Python, Data, AI, R, Streamlit, and Apps.
From your first line of Python to your next AI app.
Learn with me through practical examples and real projects.
TUTORIAL EXAMPLE
Small experiments.
Useful discoveries.
Read a little code. Change something. See what happens. That's how we turn Python, data science, and AI into things you can build.

CHANIN NANTASENAMAT, PHDRESEARCHER. EDUCATOR. BUILDER.
Hi, I'm Chanin.
Research taught me to ask questions.
Code lets me answer them.
I'm a Lead Developer Advocate for Open Source at Snowflake, creating educational content on building data apps with Streamlit and Snowflake. Before tech, I was a Professor of Bioinformatics, using Python to teach and perform research in computational drug discovery.
Since 2019, I've shared data science and AI tutorials on the Data Professor YouTube channel. Those videos have received more than 10 million views.
