There's mixed feedback to Asyncio in the community. Some people passionately hate it whilst others believe "writing async make program go fast". This debate is way too much for me to cover here right now. Though maybe I'll look at it in the future.
For me I use asyncio a …

It is exceeding easy to use it, docker is registered as a single MCP server for your client. And tools …
read morePreviously I've played with tool calling in Langchain and Python sandboxes. But recently MCP (Model Context Protocol) is front and center. So I tried to create my own github MCP in Python to integrate cursor with the github cli.
Before we get started, its good to familiarise …
read moreIn my posts earlier this year I talked about the parallelism performance on 3.13 free-threaded builds. In particular I looked at solving an advent of code problem. In How free are threads in Python now? I discovered significant performance penalties for using free-threading and a lack of tooling available …
read moreYou're probably thinking that there are already plenty of tools written in Python.
But I see that most of the popular tools like mypy and flake8 are built for development environments. In contrast, general purpose cli tools tend to be built in other languages, for example most of the docker …
I've been a little obsessed with operator overloading lately. First using |= in sqlalchemy-builder and then using | and @ in better-functools.
I didn't actually know that these qualify as DSLs, specifically what's known as "internal DSLs". Funnily enough, I'm usually not a fan of DSLs. A few reasons come to mind:
I recently put some effort into creating better-functools. It's a package that adds some tooling for functional programming in Python. And allows us to write some unique looking code in a manner similar to functional languages:
At a glance this doesn't look very "Pythonic". More complex …

It starts off with a REST API route. For example in fastAPI
@app.get("/")
def search_users(session: Session) -> list[User]:
"""Finds users optionally filter by user_id"""
statement = select(User).order_by(User.name)
return session.execute(statement).scalars().all()
Then we get asked …
