New to Python? No Problem!

I’ve got a FREE offering for you.

My cluster analysis online course uses Python programming, but don’t let that scare you for two reasons:

  1. You only need to learn a subset of Python to use it effectively for cluster analysis.

  2. You can start with my free 7-hour Python Crash Course!
    Designed for professionals with no programming background, it’ll prepare you for cluster analysis.

What folks have to say about my Python Crash Course

(BTW 👆 - I do have a SQL tutorial series on my YouTube channel.)

Greetings! I’m Your Instructor, Dave Langer.

I’m not your typical data science instructor. I believe ANY professional can (and should) build DIY data science skills. To succeed in this mission, I have to do one thing and do it well.

I have to make learning data science fun.

Yes, you read that correctly.

I won’t lie. Many find the idea of applying cluster analysis intimidating. It shouldn’t be. It’s a skill like any other. You get better with practice.

Making learning data science fun makes getting started less intimidating.

You’ve got this if you want it.
