Brian #1: pypistats.org was down, is now back, and there’s a CLI
pypistats.org is a cool site to check the download stats for Python packages.
It was down for a while, like 3 weeks?
A couple days ago, Hugo van Kemenade announced that it was back up.
With some changes in stewardship
“pypistats.org is back online! 🚀📈
Thanks to @jezdez for suggesting the @ThePSF takes stewardship and connecting the right people, to @EWDurbin for migrating, and of course to Christopher Flynn for creating and running it for all these years!”
Hugo has a CLI version, pypistats
You can give it a command for what you want to search for
recent,overall, python_major, python_minor, system
Then either a package name, a directory path, or if nothing, it will grab the current directory package via pyproject.toml or setup.cfg
very cool
Michael #2: State of Python 2025
Michael’s Themes
Python people use Python: 86% of respondents use Python as their main language
We are mostly brand-new programmers: Exactly 50% of respondents have less than two years of professional coding experience
Data science is now over half of all Python
Most still use older Python versions despite benefits of newer releases: Compelling math to make the change.
Python web devs resurgence
Forward-looking trends
Agentic AI will be wild
Async, await, and threading are becoming core to Python
Python GUIs and mobile are rising
Actionable ideas
Action 1: Learn uv
Action 2: Use the latest Python
Action 3: Learn agentic AI
Action 4: Learn to read basic Rust
Action 5: Invest in understanding threading
Action 6: Remember the newbies
Brian #3: wrapt: A Python module for decorators, wrappers and monkey patching.
“The aim of the wrapt module is to provide a transparent object proxy for Python, which can be used as the basis for the construction of function wrappers and decorator functions.
An easy to use decorator factory is provided to make it simple to create your own decorators that will behave correctly in any situation they may be used.”
Why not just use functools.wraps()?
“The wrapt module focuses very much on correctness. It therefore goes way beyond existing mechanisms such as functools.wraps() to ensure that decorators preserve introspectability, signatures, type checking abilities etc. The decorators that can be constructed using this module will work in far more scenarios than typical decorators and provide more predictable and consistent behaviour.”
There’s a bunch of blog posts from 2014 / 2015 (and kept updated) that talk about how wrapt solves many issues with traditional ways to decorate and patch things in Python, including “How you implemented your Python decorator is wrong”.
Docs are pretty good, with everything from simple wrappers to an example of building a wrapper to handle thread synchronization
Michael #4: pysentry
via Owen Lamont
Install via uv tool install pysentry-rs
Scan your Python dependencies for known security vulnerabilities with Rust-powered scanner.
PySentry audits Python projects for known security vulnerabilities by analyzing dependency files (uv.lock, poetry.lock, Pipfile.lock, pyproject.toml, Pipfile, requirements.txt) and cross-referencing them against multiple vulnerability databases. It provides comprehensive reporting with support for various output formats and filtering options.
Key Features:
Multiple Project Formats: Supports uv.lock, poetry.lock, Pipfile.lock, pyproject.toml, Pipfile, and requirements.txt files
External Resolver Integration: Leverages uv and pip-tools for accurate requirements.txt constraint solving
Multiple Data Sources:
PyPA Advisory Database (default)
PyPI JSON API
OSV.dev (Open Source Vulnerabilities)
Flexible Output for different workflows: Human-readable, JSON, SARIF, and Markdown formats
Performance Focused:
Written in Rust for speed
Async/concurrent processing
Multi-tier intelligent caching (vulnerability data + resolved dependencies)
Comprehensive Filtering:
Severity levels (low, medium, high, critical)
Dependency scopes (main only vs all [optional, dev, prod, etc] dependencies)
Direct vs. transitive dependencies
Enterprise Ready: SARIF output for IDE/CI integration
I tried it on pythonbytes.fm and found only one issue, sadly can’t be fixed:
PYSENTRY SECURITY AUDIT
=======================
SUMMARY: 89 packages scanned • 1 vulnerable • 1 vulnerabilities found
SEVERITY: 1 LOW
UNFIXABLE: 1 vulnerabilities cannot be fixed
VULNERABILITIES
---------------
1. PYSEC-2022-43059 aiohttp v3.12.15 [LOW] [source: pypa-zip]
AIOHTTP 3.8.1 can report a "ValueError: Invalid IPv6 URL" outcome, which can lead to a Denial of Service (DoS). NOTE:...
Scan completed

Michael:
I’ve been rumbling with rumdl.
Ruben fixed one of my complaints about it with issue #58.
Config seems like it might be off. Here’s mine .rumdl.toml.
I’ve been using it on the upcoming Talk Python in Production book
Read the first third online and get notified when its out.
20 or so Markdown files
45,000 words of content
I asked if 3.13.6 would be the last 3.13 release? No.
Thanks Hugo.
Python 3.13.7 is now out.
