Unfortunately, I might be a bad person to answer that question. I'm 52, and have been programming since high school, not as a professional developer, but just using programming as a tool. So I learned data analysis long before learning Python, just through my general science education and work. The result is that I don't really know what a good modern tutorial is.

The old timers would just hand you a copy of Numerical Recipes and wish you good luck. ;-)
