Folks: for the last-time, a pandas.DataFrame is one-dimensional. Yes, the docs call the pandas.DataFrame a “[t]wo-dimensional, size-mutable, potentially heterogeneous tabular data.” The docs are wrong.

As we all know (or, at least, as I've been trying to tell everyone,) generators in Python are an extremely powerful API design technique. A generator represents the linear decomposition of a single computation into multiple parts, and such decomposition proves very useful in practice.

How do we speed up a critical missing operation in pandas, the cumulative index max, and what does this tell us about the compromises and considerations we must bring to optimizing our code?

Okay, so that's plainly preposterous. How is int related to list at all, much less float to tuple? Sure, int is a collection type—just one that you can't iterate over—wait, what? int is a collection type‽ What's going on here? Join us for this keynote to find out what this all means, and why it...

When designing an API, how do you restrict your users to your public interface and keep their filthy hands off your internal implementation details? Sadly, the richness of Python's runtime makes this remarkably difficult.
