I wish I had the time and energy to play with #pyodide more, I could try adding #shapely to #pyp5js ...

🎁 Hey, let's give away software for free! Just throw some #HTML, #JavaScript, and a sprinkle of #WebAssembly into the void of the internet, and voilà, you've gifted a ticking time bomb to the world! 🤡 #Pyodide to the rescue, because who doesn't want Python apps running in a browser while you sip margaritas on a beach, free from the corporate yoke of... paying hosting bills. 🌴💸

Pydantic Releases Sandboxed Python Execution Server for AI Agents via Model Context Protocol
#AI #Pydantic #PydanticAI #MCP #ModelContextProtocol #Python #LLMs #AgenticAI #OpenSource #DevTools #Pyodide #Deno #Sandboxing #AISecurity #AIIntegration
The #MCP Run #Python package is an MCP server that allows agents to execute Python code in a secure, sandboxed environment. It uses #Pyodide to run Python code in a #JavaScript environment with Deno, isolating execution from the host system. https://ai.pydantic.dev/mcp/run-python/
An unplanned product of the #IETFHackathon was a new #CoAP tool: https://coap.amsuess.com/view/##coaps+ws://demo.coap.amsuess.com/.well-known/core is now usable as a browser tool to fetch CoAP resources.
It is not pretty, and takes a few seconds to load, but then it's just 150 lines of code, building on aiocoap and #pyodide.

In this presentation, I showcase how WebAssembly (WASM) brings interactive coding directly into slide decks using Python (via Pyodide) through quarto-live - the official Posit Quarto WebAssembly backend by George Stagg.
#PyScript now has experimental support for #PygameCE !
Has anyone seen it in the wild?

TIL there is pyodide (https://pyodide.org/).
Well, should I port the FlightBox frontend and the Abelbeck Aviation Checklist to Python? 🤔
Con:
- need to dive into a new framework
- dump JS work so far
Pro:
- back on home ground! 🙂
- simplifies the code base (JS is rather awkward)
This model has me excited, web pages that asynchronously load #Python and #Pyodide for a seamless experience for the user while allowing developers to use Python.

Recently I've been working on getting #polars running in #pyodide. This was a fun one, even requiring patches to LLVM's #wasm writer! Everything has now been upstreamed and earlier this week Pyodide v0.27.0 released, including a Wasm build of Polars usable in the Pyodide REPL, Shinylive and Quarto Live 🎉
![A screenshot of a Shinylive app using Polars code:
from shiny import App, render, ui
import polars as pl
from pathlib import Path
app_ui = ui.page_fluid(
ui.input_select("cyl", "Select Cylinders", choices=["4", "6", "8"]),
ui.output_data_frame("filtered_data")
)
def server(input, output, session):
df = pl.read_csv(Path(__file__).parent / "mtcars.csv")
@output
@render.data_frame
def filtered_data():
return (df
.filter(pl.col("cyl") == int(input.cyl()))
.select(["mpg", "cyl", "hp"]))

A couple of days ago, I shared a sneak peek of my latest project: https://fosstodon.org/@saiyalamarty/113388133530826071. Today, I’m excited to announce that we’ve added a waitlist to the landing page!
If you’re interested in being among the first to try out Pykernel and joining the beta program, sign up now to secure your spot.
🎓 Excited to speak at @pyOpenSci's Fall Festival! Join me for insights on the future of #DataScience education using #WebAssembly tools like #Pyodide & #webR with #Quarto.
📅 Nov 1st, Workshop: "Reproducible reports and presentations"
Perfect for educators & practitioners! #Python #rstats
📚 Get a head start!

How about a #Python "Tetris" with #pyodide in your browser with pyp5js?
#pyp5js code at: https://gist.github.com/villares/321c087b517cffee026ab828aabc35f0

You know you're in deep when you're debugging by writing LLVM IR by hand. Totally worth it, though.
This requires a custom build of LLVM and rustc to compile right now, but here is a sneak preview of #polars on #pyodide, running under #wasm.

#LazyFedi There was a very cool blog post by some of the JupyterLite authors describing the technical hurdles they had to overcome to run Jupyter on Pyodide (things like running a Tornado web server without blocking the main thread etc) but I can't seem to find it... @jtp @ProjectJupyter or anyone, any clue?
#Pyodide is a port of CPython to WebAssembly/Emscripten.
Funny hackathon.
But do you want to invest time & money to dance on top of that ?
