Cython as a Game Changer for Efficiency - Alex Orlov

• For performance problem:

• Cython is a superset of the Python programming language, designed to give C-like performance with code which is mostly written in Python.

Modern Python Dictionaries A confluence of a dozen great ideas - Raymond Hettinger

Intro

Separate Chaining

• Basical concept of hashing

Dynamic Resizing

• More entries, more buckets, which incurs resizing
• When resizing, hash values of all entries requied
• Make resizing faster by caching the hash value,

Faster Matching

• Do cheap equality tests first

Open Addressing

• Flatten entries from the separate chaining

Deleted Entries

Multiple Hashing

• Linear probing will end up with catastrophic linear pile-up
• Re-hash to other locations based on the hash value and the number of probes

Early-Out For Lookups

• versioning for dict

Compact Dict

Key Sharing Dictionary

• Share hash values and keys

Static Types for Python - Jukka Lehtosalo, David Fisher

Motivation

Demo

How mypy works

Annotating a codebase

• Instead, use bottom-up approach:

$ mypy util.py
# Make mypy consistent gragually
$ mypy util.py view.py

• Even though, there are some cases that need ignore imports

Keep your code mypy clean
