Pyodide
=======

Python with the scientific stack, compiled to WebAssembly.

Pyodide may be used in any context where you want to run Python inside a web
browser.

Pyodide brings the Python 3.9 runtime to the browser via WebAssembly, thanks to
`Emscripten <https://emscripten.org/>`_.
It builds the Python scientific stack including NumPy, Pandas, Matplotlib, SciPy, and
scikit-learn. Over 75 packages are currently available. In addition, it's
possible to install pure Python wheels from PyPI.

Pyodide provides transparent conversion of objects between JavaScript and
Python. When used inside a browser, Python has full access to the Web APIs.

Pyodide development happens on GitHub: `github.com/pyodide/pyodide <https://github.com/pyodide/pyodide>`_

Try Pyodide (no installation needed)
------------------------------------

Try Pyodide in a
`REPL <https://pyodide.org/en/stable/console.html>`_ directly in
your browser.
