The Dictionary Even Mightier

Description

Since my “Mighty Dictionary” talk at PyCon 2010, the Python dictionary has evolved dramatically. Come learn about all of the the improvements, up to and including the re-architecture that has just landed with Python 3.6! The talk will discuss iterable views, the dictionary’s dedicated comprehension syntax, random key ordering, the special key-sharing dictionary designed to underlie object collections, and, most famously of all, the new “compact dictionary” that cuts dictionary storage substantially — and carries a fascinating side-effect.

Each new feature that the talk discusses will be motivated by considering the trade-offs inherent in hash table data structure design, and followed up with hints about how you can now use the dictionary even more effectively in your own code!
