Why do I get the error: No module named 'pyodide'

I installed pyodide.http but I cannot import it. What did I do wrong?

C:\Users\malik>pip install pyodide.http

The pyodide Python module is a module that makes using Python easier in the browser and in particular includes the Python <-> Javascript Foreign Function Interface (FFI).

Outside of the browser, you can install it from the pyodide-py package,

pip install pyodide-py

However most of its functionality doesn't make sense outside of the browser (or Node.js runtime), so it is mostly intended to avoid import errors, in code that imports but does not directly need it.

Similarly pyodide-http is intended for monkeypatching request & HTTP client-related libraries for the browser. So I'm not sure why you are trying to install it outside of the browser.

If you are running in the browser, you would install pyodide-http with micropip rather than pip, and the pyodide module is included by default (in the Pyodide distribution).
