30 things I’ve learned from 30 years as a Python freelancer
30 years! It’s hard to believe, but it was in December 1995 (i.e., 30 years ago) that I went freelance, giving up a stable corporate paycheck. And somehow, I’ve managed to make it work: During that time, I’ve gotten married, bought a house, raised three children, gone on numerous vacations, and generally enjoyed a good…

Want to learn uv?
You’ve probably heard about uv: But using uv isn’t just about learning a few commands. It’s about changing how you think about packaging, and what commands you run on a regular basis. That’s why I’ve created a free uv crash course. Every day, for 12 days, you’ll get insights into how to (and how not…

Your personal mentor for Python and Pandas
I’ve been teaching Python and Pandas for decades — in companies, at conferences, and on YouTube — and I keep hearing the same frustrations everywhere I go: That’s why I’ve spent the last few months completely rebuilding LernerPython.com. It’s a complete, structured learning experience, not just a set of courses. Instead of leaving you on…

You’re probably using uv wrong
Bottom line: If you’re typing uv pip install, you’re treating uv as a faster pip and missing the point. uv is built around projects: run uv init myproj to create a pyproject.toml, uv add to record dependencies, and uv run to execute your code. Do that, and you can ignore pip, venv, and pyenv entirely.…

How to conference
I love conferences. I enjoy everything about them — the nonstop stream of learning, the chance to see old friends and meet new ones, and just generally to be around a lot of interesting, smart, and fun people. And yes, as a trainer, I also enjoy getting a chance to teach — which is fun…

My newest course: HOPPy (Hands-on Projects in Python)
Congratulations! You’ve finished a Python course, or even two. You’re now a certified Python programmer. And yet, when it comes time to start a new Python project, you aren’t sure where to start. The blank screen in front of you doesn’t fill you with excitement and creativity. Rather, it fills you with self-doubt and dread.…

Prepare yourself for a better career, with my new Python learning memberships
For years, students and clients have asked me for a membership program that includes all of my products. And for years, I’ve said, “No.” Why not? Because I didn’t just want to offer access to my courses. I wanted to make something more than that — with a constant array of new content, interactions among…

Like many online entrepreneurs, I’ve experimented with a host of different products over the years, some…
