PyScript

What is PyScript

Summary

PyScript is a Pythonic alternative to Scratch, JSFiddle, and other "easy to use" programming frameworks, with the goal of making the web a friendly, hackable place where anyone can author interesting and interactive applications.

To get started see the getting started tutorial.

For examples see here.

Longer Version

PyScript is a meta project that aims to combine multiple open technologies into a framework that allows users to create sophisticated browser applications with Python. It integrates seamlessly with the way the DOM works in the browser and allows users to add Python logic in a way that feels natural both to web and Python developers.

Try PyScript

To try PyScript, import the appropriate pyscript files to your html page with:

<linkrel="stylesheet" href="https://pyscript.net/alpha/pyscript.css" /><scriptdefersrc="https://pyscript.net/alpha/pyscript.js"></script>

You can then use PyScript components in your html page. PyScript currently implements the following elements:

  • <py-script>: can be used to define python code that is executable within the web page. The element itself is not rendered to the page and is only used to add logic
  • <py-repl>: creates a REPL component that is rendered to the page as a code editor and allows users to write executable code

Check out the the examples directory folder for more examples on how to use it, all you need to do is open them in Chrome.

Notes

  • This is an extremely experimental project, so expect things to break!
  • PyScript has been only tested on Chrome at the moment.
