use python in javascript

It is not possible to directly use Python in JavaScript as they are two different programming languages. However, there are ways to run Python code within a JavaScript application.

One approach is to use a transpiler that can convert Python code into JavaScript code. Two popular options for this are Pyodide and Brython.

Pyodide is an experimental project from Mozilla that allows running Python code in the browser using WebAssembly. With Pyodide, Python code can be called directly from JavaScript.

index.tsx
// Load the Pyodide runtime
await loadPyodide({ indexURL: 'https://cdn.jsdelivr.net/pyodide/v0.17.0/full/' });

// Run Python code
const result = await pyodide.runPython('print("Hello from Python!")');
console.log(result); // Hello from Python!

Brython is another option that compiles Python to JavaScript using a Python-to-JS compiler. Brython is designed to be more lightweight than Pyodide and can be used for web development or interactivity.

<!-- Load the Brython library -->
<script src="https://cdn.jsdelivr.net/npm/brython@3.9.5/brython.js"></script>

<!-- Define a script tag with Python code -->
<script type="text/python">
print("Hello from Python!")
</script>

<!-- Run the script -->
<script>
brython()
</script>

Both Pyodide and Brython have their own limitations and may not be suitable for all use cases. It is important to assess the requirements of your application before deciding which approach to use.
