## In brief

- Tim Peters, a long-time Python contributor and creator of Timsort, died at age 74 in Ashland, Wisconsin, according to a DEV Community article.
- Guido van Rossum announced the death on discuss.python.org, reporting it somewhat delayed, per LWN.net.
- Peters is best known for writing the Zen of Python (PEP 20) and for his work on Timsort and the Python Cookbook 2nd Edition.

## Why it matters

Peters wrote Timsort, which Python uses for sorting, and PEP 20 (the Zen of Python), so his work is part of everyday Python code and practice.

## What developers say

Commenters on Hacker News mourn Peters and recall his influence on their early Python years, his Usenet posts, and his mentoring. Several cite the Zen of Python and Timsort as lasting parts of their work. A few note that a black bar was appropriate, and one criticises Guido van Rossum for not defending Peters during past conflicts with Python leadership. (sentiment: mixed)
