In Memoriam: Tim Peters 1952–2026
Guido van Rossum conveys the sad (and somewhat delayed) news of the passing of Tim Peters. It's hard to overestimate Tim's influence on Python.
Why am I seeing this Ranked on source trust — LWN
It ranks mainly on source trust: LWN is the most reliable outlet we track on this subject, and is the only one on the story so far.
Single-sourced. No second organisation has confirmed it yet.
Link-outLink-out, because only one organisation carries it and no first-party source is on it and the subject could not be identified from the text. Link-out means we point at the publisher and say nothing of our own.
| Factor | Weight | Score | Contribution | Where it came from |
|---|---|---|---|---|
| Corroboration | 0.35 | 0.39 | +0.135 28% | 1 independent org on the story. Tier-3 aggregators never corroborate — they can show something is circulating, never that it is true. |
| Source trustleads | 0.25 | 0.85 | +0.212 45% | LWN is the highest-trust source on this story. Trust is taken from the best source, not averaged. |
| Pickup rate | 0.20 | 0.00 | +0.000 0% | One counted organisation, so there is no spread to measure — nothing has picked this up to set a rate. |
| Freshness | 0.20 | 0.64 | +0.129 27% | Halves every 10 hours from the newest item on the story. This is the only factor that rewards a story for nothing more than being recent. |
Corroboration counts distinct organisations, once each, and only from tiers 1 and 2. Freshness halves every 10 hours, so this ranking is a snapshot and will differ at the next build.

Guido van Rossum announced his death, noting that Peters joined the project early in Python's history and shaped core language decisions. Peters advocated for mixed arithmetic between integers and floats, a feature now standard in the language, and served as both mentor and co-designer alongside van Rossum.
Peters is widely recognized as the author of PEP 20, the Zen of Python, a set of principles that guide Python's design philosophy. This document remains one of the most cited references in the Python community and reflects his thinking about how the language should evolve and be used.
Van Rossum emphasized that Peters' contributions extended far beyond any single feature or document. His involvement in Python spanned from the language's earliest days, and he maintained an active role in its development throughout his life, leaving a lasting impact on how millions of developers write code today.
What happened
Guido van Rossum conveys the sad (and somewhat delayed) news of the passing of Tim Peters. It's hard to overestimate Tim's influence on Python. He's probably best known for writing the Zen of Python ( PEP 20 ), but to me he was a mentor and language co-designer long before that. Tim found Python not long after its initial release. His first deed was to convince me that Python should support mixed arithmetic between int and float, because most users would expect them to work that way.
