Welcome to issue 749 of Python Weekly. Let's get straight to the links this week.

One editor for writers, developers, and agents

Your docs have more contributors than ever. Engineers, PMs, support, marketing, and now AI agents. But most documentation tools force a choice: an accessible editor for the whole team, or the rigor of git-based version control for developers. That tradeoff slows everyone down.

Mintlify's editor removes the tradeoff. Writers get a visual WYSIWYG experience with slash commands and editable navigation. Developers keep their git-native workflow. Every visual edit is a clean commit, every commit appears in the editor. Changes flow both ways.

The editor also brings live collaboration and AI agents as first-class contributors:

  • WYSIWYG editing with no markdown syntax required

  • Real-time multiplayer for war room-style doc sessions

  • MCP support so your AI can edit alongside your team

  • Two-way git sync that preserves a single source of truth

The best documentation is written by everyone who has context. That's your whole team. And now, your agents. Try it at mintlify.com.


News

The Steering Council says the CPython JIT has reached the point where it needs a formal Standards Track PEP covering guarantees, maintenance, and impact on redistributors before it can be treated as a supported feature. Until that PEP is accepted, they want no new JIT features or optimizations on main, and if no PEP is resolved within six months, the JIT code is to be removed from the main branch.


Articles, Tutorials and Talks

Simon Willison describes micropython-wasm, an experiment that runs MicroPython inside WebAssembly, allowing Python code to execute in a fresh sandbox with memory limits and host-controlled I/O. The approach is already powering a Datasette Agent plugin, though it remains alpha software and has not yet been vetted for safely running untrusted code.

A perceptron explained from scratch in Python, with interactive demos. Learn weights, bias, the decision boundary, epochs, learning rate, and why we normalize data.

A hands-on guide to instrumenting a Python LLM app with OpenTelemetry, tracing agent workflows, understanding the developing GenAI ecosystem, and visualizing telemetry in SigNoz.

So, you want to keep a sorted index in DynamoDB, but for whatever reason – usually throughput-related – it won't fit on a single partition. What do you do? Today, we look at the available solutions, do the math, and find out which is best.

Python library maintainers don't need to run every type checker on their source code. A better approach is to run one preferred type checker internally while validating public APIs and test suites across multiple tools such as mypy, Pyrefly, Pyright, ty, and Zuban. The article uses Polars as an example, showing that supporting multiple type checkers in implementation code can create significant maintenance overhead, while multi-checker API compatibility provides the greatest benefit to users.

This article demonstrates how to build a Model Context Protocol (MCP) server using Django and django-allauth, with OpenID Connect (OIDC) authentication handled by the allauth.idp package. It shows how MCP hosts such as Claude can dynamically register and authenticate clients without relying on separate third-party identity providers.

In this video, we'll look at how to setup django-q2 using a Redis task broker running in a Docker container. This gives a more efficient and production-ready setup than using the ORM.

The post highlights a set of Python libraries that work natively with Polars, letting you stay in the Polars ecosystem for validation, tables, visualization, and LLM-assisted analysis.
