import { useEffect, useState } from "react";

export default function Home() {
  const [hydrated, setHydrated] = useState(false);
  useEffect(() => {
    setHydrated(true);
  }, []);
  if (!hydrated) {
    // Returns null on first render, so the client and server match
    return null;
  }
  return (
    <div>
      test
      <py-script>
        for i in range(9):{"\n"} print(i){"\n"}
        {"\n"}

What did you try, what did work/didn't work
it's supposed to work in the broswser, so it probably works, but you'll have to explore how

import type { Metadata } from "next";
import { Inter } from "next/font/google";
import "./globals.css";
import Script from "next/script";
import { NextScript } from "next/document";

const inter = Inter({ subsets: ["latin"] });

export const metadata: Metadata = {
  title: "Create Next App",
  description: "Generated by create next app",
};

export default function RootLayout({
  children,
}: Readonly<{
  children: React.ReactNode;
}>) {
  return (
    <html lang="en">
      <link rel="stylesheet" href="https://pyscript.net/latest/pyscript.css" />
      <Script
        defer
        src="https://pyscript.net/latest/pyscript.js"
        strategy="beforeInteractive"
      />
      <body className={inter.className}>
        {children}
        <NextScript />
      </body>
    </html>

semmes to be blending Pages and App Router, can you try on a freshly created Next.js app maybe ?
In&OutOP
i did
Eric Burel
are you sure the issue is related with PyScript?
In&OutOP
let me remove it
yup, it is
Eric Burel
what's NextScript from "next/document" ?
In&OutOP
works without it
Eric Burel
this tutorial is for the pages router you should try with the pages router rather than the app router then
In&OutOP
ah alr, how to get pages folder in next 14?
Eric Burel
mkdir pages
rm app
it its retrocompatible
In&OutOP
oh just that?

Eric Burel

export default function Home() {
  return (
    <div>
      test
      <py-script>
        for i in range(9): print(i) def func(): print('function works')
      </py-script>
    </div>
