Teaching Python and Data Science around the world

Hi, I’m Reuven Lerner.  I help developers around the world to become more fluent in Python.   I’d love to find ways to make you a better developer, too!

Most days, I work on-site with companies around the world (US, Europe, Israel, and China), teaching their engineers and staff.  If you want your team ​to write better, shorter Python code in less time, then let's talk!

​And if you're an individual?  Read on, to learn about my various online training options.

My Services

Corporate Python Training

No matter your team's Python level, I can help you do more in less time.

Weekly Python Exercise

Do you still need to search Stack Overflow several times each day, because your Python isn't fluent? Weekly Python Exercise is here to help you, with a family of 15-week courses for both newcomers to Python and experienced developers.

Online Python Video Courses

Do you want to take the courses I give at the world’s biggest companies? Now you can, with my online courses. Learn from your home or office!

Weekly Python Exercise

"Weekly Python Exercise" is a set of 15-week courses that ​make you a more fluent Python programmer.  

How It Works: Every Tuesday, you get a new problem sent to you via e-mail.  The following Monday, you get a detailed solution, complete with explanations.  In between, you can exchange ideas and solutions with others in your cohort.​ And every month​, you can join live office hours, asking questions about the exercises or ​Python in general.

WPE is all about improving your Python, one week at a time.  New cohorts open every 1-2 months, at the beginner and advanced levels.  Students say that WPE provided​ the boost they needed to make them better Python developers.

How I'm Different

Interactive

My courses are highly interactive, with numerous exercises and opportunities for discussion.  I rarely use slides, instead live-coding into the Jupyter notebook as I ​demonstrate the techniques I’m teaching.  After class each day, I send my Jupyter notebooks to my students, for review and future reference.

​Learning by doing

​I know that people learn best not by listening to long lectures, but by actually trying, failing, and then understanding where they went wrong. That's why my courses consist of 30-40% hands-on labs. Each exercise will push you to understand Python at a deeper level, contextualizing the ideas we've discussed.
