pyodide-py

Pyodide Python package

A Python package providing core interpreter functionality for Pyodide.

This package is an integral part of the Pyodide runtime which cannot start without it. Install in a native Python for type checking or testing purposes. Some of the functionality is missing when imported in a native Python, but for the APIs we either provide reimplementations or nonfunctional type stubs.

Design information for Pyodide contributors

This directory consists of two Python packages py/_pyodide and py/pyodide. The difference between these packages is when they are imported. They are both imported by core/pyodide as a part of setting up the Pyodide/javascript foreign function interface.

py/_pyodide is imported as the first step after initializing the CPython interpreter. py/_pyodide cannot have any import time dependencies other than the CPython stdlib.

py/pyodide is imported as the final step of core/pyodide. It has an import time dependency on _pyodide_core which is a Python C extension assembled by core/pyodide to serve the needs of py/pyodide.
