Welcome to issue 682 of Python Weekly. Happy New Year! I hope you had a great holiday and took some time off to recharge.

Learn how to make AI work for you

AI won’t take your job, but a person using AI might. That’s why 800,000+ professionals read The Rundown AI – the free newsletter that keeps you updated on the latest AI news and teaches you how to use it in just 5 minutes a day.

Articles, Tutorials and Talks

The video showcases the process of building an AI coding tutor/assistant using Parlant, a framework for guided LLM agents. The project includes features like roadmap generation, resource tracking, and quiz creation, demonstrating the integration of AI tools with a Python backend and Streamlit frontend.

The article explores iteratively asking an LLM to "write better code" for a Python task, resulting in significant performance improvements through algorithmic optimizations and parallelization. While initial iterations yielded substantial speedups, later iterations led to overengineered "enterprise-level" features, highlighting the importance of specific prompting for desired outcomes in LLM-assisted coding.

Debugging a FastAPI app in VSCode is tricky because the code is run via a tool like uvicorn , and you typically interact with the API via curl statements or a browser. This video shows you how to setup debugging for your FastAPI app.

The article discusses a technique for symbolic execution in Python by overloading the bool method, allowing non-overloadable syntax to become overloadable. This approach enables recording paths through Python code and achieving symbolic execution without extensive modifications, particularly useful for integrating with Z3 solver and metaprogramming.

GitClear's changelog generator helps devs ditch the busywork of scouring git history to recall what was implemented. Snap Changelogs go on your website, GitHub profile, or anywhere a PNG can fit. SPONSOR

The post recounts debugging a complex multi-threading bug in a Python web framework, initially misdiagnosed as a shared mutable state issue. The author later discovers the true cause: an engine object inadvertently attached to a global class definition instead of a local namespace, leading to unexpected data leakage between requests in a multi-threaded environment.

An overview on how to do complex filtering in Django with Subquery.

The article discusses using symbolic models in Python for hardware design verification, focusing on an image downscaler example. It compares traditional hardware design flows with symbolic modeling, demonstrating how the latter can simplify debugging and verification by tracking data origins throughout the design process.

PyPI introduced a "Project Quarantine" feature to combat malware, allowing administrators to mark potentially harmful projects as quarantined, preventing easy installation while preserving project data. The post discusses the implementation details, usage statistics, and future plans for automation, aiming to reduce the time malicious projects remain accessible to users.

Implementing LAPACK routines for numerical computation in web applications.

The article discusses how to use the objgraph library to debug memory leaks in Python. It also provides a number of tips and tricks for debugging memory leaks, such as using signal handlers to trigger ad-hoc behavior in a program and using a separate script to manage the state of the debugging session.

The video demonstrates how beginners can use AI to code in Python, covering setup and three projects: data scraping, bulk image editing, and creating a data dashboard.

This is a post about leadership power tools. It discusses SQL and statistics. In order to make better decisions, leaders should be comfortable with extracting and interpreting data from stores. SQL is a powerful tool that can be used to query data. Statistical methods can be used to interpret data and make better decisions.
