Run Python code directly in the browser. Try it out!

Install react-py with:

npm i react-py

Then, wrap your app in a PythonProvider component.

import { PythonProvider } from "react-py";

function App() {
  return (
    // Add the provider to your app
    <PythonProvider>
      <Codeblock />
    </PythonProvider>
  );
}

render(<App />, document.getElementById("root"));

Using the usePython hook, you can run code and access both stdout and stderr. For full usage instructions, see the usage docs.

Basic example Interrupting execution

Most of the Python standard library is functional, except from some modules. The following modules can be imported, but are not functional due to the limitations of the WebAssembly VM:

• multiprocessing
• threading
• sockets

Learn more about the limitations here.

• Add additional examples
• Ability to run python in Web Workers
• Extended API for custom configuration
