# July 2025: Profiling Python programs / uv, simplified

Double-header for July!

## Profiling Python programs

If your Python program runs slowly and/or is using too much memory, don’t just go haring off trying to optimize it based on eyeballing the code and taking a guess. There is a variety of tools available to help you zero in on which portions of your program are the bottleneck, and that’s the first and most important step of fixing your speed problems. We’ll try out py-spy and memray.

and

## uv (simplified)

We had an introduction to uv last year - the package and Python installer that’s conquering the Python world, but it was a lot to take in. In case it went by in a blur, we’re going to do a re-introduction that’s intentionally slimmed-down and slower. (But we’ll also add in a few terribly nice new features, too.)

## Location: Innovation Hub

We’re back in person!

We 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 been exposed to COVID, or 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, discord.gg/9SgTh3T, and click on the General voice chat link. You may need to install the Discord desktop app rather than just using the web interface.

DDL is dedicated to discussion of technology and techniques related to dynamic programming languages: Python, Perl, Ruby, PHP, JavaScript, and sometimes something more exotic! These languages are fun and easy to get started with, yet powerful enough for all manner of professional use, and our members span the full range of experience with them.

We always leave time for general conversation and questions. Come try one of the most interactive groups around!

The Dayton Dynamic Languages User Group meets the 2nd Wednesday of each month from 7 to 9 PM, online and at Dayton's Innovation Hub (part of the renovated Arcade conmples). Use the General voice channel at discord.gg/9SgTh3T

We are a Special Interest Group (SIG) of the Dayton Microcomputer Association. http://d8ndl.org
