Pyodide is a Python distribution for the browser and Node.js based on WebAssembly.

## What is Pyodide?

Pyodide is a port of CPython to WebAssembly/[Emscripten](https://emscripten.org/).

Pyodide makes it possible to install and run Python packages in the browser with

[micropip](https://micropip.pyodide.org/). Any pure

Python package with a wheel available on PyPi is supported. Many packages with C

extensions have also been ported for use with Pyodide. These include many

general-purpose packages such as regex, PyYAML, lxml and scientific Python

packages including NumPy, pandas, SciPy, Matplotlib, and scikit-learn.

Pyodide comes with a robust Javascript ⟺ Python foreign function interface so

that you can freely mix these two languages in your code with minimal friction.

This includes full support for error handling, async/await, and much more.

When used inside a browser, Python has full access to the Web APIs.

## Try Pyodide (no installation needed)

Try Pyodide in a

[REPL](https://pyodide.org/en/stable/console.html) directly in

your browser. For further information, see the

[documentation](https://pyodide.org/en/stable/).

## Getting Started

Pyodide offers three different ways to get started depending on your needs and

technical resources. These include:

- Use a hosted distribution of Pyodide: see the [Getting

  Started](https://pyodide.org/en/stable/usage/quickstart.html) documentation.

- Download a version of Pyodide from the [releases

  page](https://github.com/pyodide/pyodide/releases/) and serve it

  with a web server.

- [Build Pyodide from source](https://pyodide.org/en/stable/development/building-from-sources.html)

  - Build natively with `make`: primarily for Linux users who want to

    experiment or contribute back to the project.

  - [Use a Docker image](https://pyodide.org/en/stable/development/building-from-sources.html#using-docker):

    recommended for Windows and macOS users and for Linux users who prefer a

    Debian-based Docker image with the dependencies already installed.

## History

Pyodide was created in 2018 by [Michael Droettboom](https://github.com/mdboom)

at Mozilla as part of the [Iodide

project](https://github.com/iodide-project/iodide). Iodide is an experimental

web-based notebook environment for literate scientific computing and

communication.

Iodide is no longer maintained. If you want to use Pyodide in an interactive

client-side notebook, see [Pyodide notebook

environments](https://pyodide.org/en/stable/project/related-projects.html#notebook-environments-ides-repls).

## Contributing

Please view the [contributing

guide](https://pyodide.org/en/stable/development/contributing.html) for tips

on filing issues, making changes, and submitting pull requests. Pyodide is an

independent and community-driven open-source project. The decision-making

process is outlined in the [Project

governance](https://pyodide.org/en/stable/project/governance.html).
