File System

Some internal Pyodide file system methods are exposed.

For more info, see the API reference docs.

import { usePython } from 'react-py'

function Codeblock() {
  const { readFile, writeFile, mkdir, rmdir ... } = usePython()

  function read() {
    const file = readFile('/hello.txt')
    console.log(file)
  }

  function write() {
    const data = 'hello world!'
    writeFile('/hello.txt', data)
  }

  function createDir() {
    mkdir('lib')
  }

  function deleteDir() {
    rmdir('cruft')
  }

  ...
}

Using multiple files

You can use Custom Modules to make use of multiple files:
