Workshop: Processing Large Data with Pandas

Pandas has become an incredibly popular Python package for processing data. We’ve had brief mentions of it before, but this month we have a proper workshop by a subject matter expert, Dayton’s own Evelyn Boettcher!

In this tutorial, we will:

  • Learn how Python uses memory with Pandas
  • How to reduce the Pandas’ dataframe memory footprint.
  • Learn what data types are
  • Speed up reading in csv files by using categories
  • Reduce the memory footprint by 90%

This is a hands-on workshop - bring a laptop if you can!

New meeting location!

Innovation Hub - not Brixx!

We’ve begun to meet in the Innovation Hub, a gorgeous new facility that’s part of the renovated Dayton Arcade complex. Enter through the doors that face the Wright Stop Plaza bus hub.

Street parking is free in the evening. I usually park on Ludlow Street.


if for any reason coming downtown doesn’t work for you (for instance, you’ve converted yourself to purely digital format and now exist as a set of cloud-hosted algorithms), we’ll be online as well!

Join us at 7 PM EDT on the PyFri Discord channel,, and click on the General voice chat link. You may need to install the Discord desktop app rather than just using the web interface.
