Get return from .mjs script to Python

I need to execute .mjs script about 200 times with another parameters (changableParametr):

import { Connection, PublicKey } from "@solana/web3.js";
import { Metadata } from "@metaplex-foundation/mpl-token-metadata";
const connection = new Connection("https://api.mainnet-beta.solana.com");
(async () => {
   let mintPubkey = new PublicKey(changableParametr);
   let tokenmetaPubkey = await Metadata.getPDA(mintPubkey);
   const tokenmeta = await Metadata.load(connection, tokenmetaPubkey);
   console.log(tokenmeta);
   })();

How get result to Python? I thought to use multiprocessing. Maybe expand this .mjs script to make .json file, because i need only one string from result. What is the easiest method to do this?
