PyData NYC 2014
SQL is still the bread-and-butter of the data world, and data analysts/scientists/engineers need to have some familiarity with it as the world runs on relational databases.

When first learning pandas (and coming from a database background), I found myself wanting to be able to compare equivalent pandas and SQL statements side-by-side, knowing that it would allow me to pick up the library quickly, but most importantly, apply it to my workflow.

This tutorial will provide an introduction to both syntaxes, allowing those inexperienced with either SQL or pandas to learn a bit of both, while also bridging the gap between the two, so that practitioners of one can learn the other from their perspective. Additionally, I'll discuss the tradeoffs between each and why one might be better suited for some tasks than the other. 00:00 Welcome!

One of the best Pandas talks I've seen.

I have been waiting for this for years! Ok, it felt like years. Maybe a year or so. Anyway, just great!

Excellent equivalents of SQL to Pandas querying are mentioned. Thank you. However a minor correction, at about 17.5 minutes into your talk....the x axis in Pandas dataFrame is axix 1, and the y axis of the dataFrame is axis zero.
