Hands-On Python Presentation Night

May 3, 2018 · San Francisco, United States of America

This week's talk: Python Performance Investigation by Example

Occasionally we’ll find that some bit of Python we’ve written doesn’t run as fast as we’d like, what can we do? Performance bottlenecks aren’t always intuitive or easy to spot by reading code so we need to collect data with profiling. Once we’ve identified the bottleneck we’ll need to change our approach, but what options are faster than others?

This talk illustrates a Python performance investigation and improvements using an Advent of Code programming challenge. I’ll walk through starting from a slow (but correct) solution, look at profiling data to investigate why it’s slow, and explore multiple paths for improving performance, including more efficient algorithms and using third-party tools like Cython. You’ll leave this talk with a recipe for analyzing Python performance and information about some options for improved performance.

Meet your speaker: Matt Davis is an engineer on the Data Platform team at Clover Health and a longtime PyLadies mentor. Clover Health is using Python in all systems, our mission is making data accessible to those who need it and keeping data flowing smoothly between sources and sites of use.

Matt has been using Python to work with data in science and at startups since 2008, after getting degrees in Astronomy and Aerospace Engineering. He maintains some moderately popular open-source Python libraries, including SnakeViz and Palettable. Away from computers, he likes getting outdoors and taking photos.
