typescript 文件中的 python 脚本

Question

how do I use my python script in a typescript file? Like how do I link it? I have to traverse a xml file which I have a python code which updates some details and wanted to use it in the typescript server file.

Like the server should update some details in a xml file. this update functionality is implemented in python and I wanted to use it in the typescript server code.

You can run the python script in node using exec() : https://nodejs.org/api/child_process.html#child_processexeccommand-options-callback

A minimal example assuming you have python3 installed on the machine running your node script could be:

// shell.py

print('printed in python')

// server.js

import {exec} from 'child_process'
//if you don't use module use this line instead:
// const { exec } = require('child_process')

exec('python3 shell.py', (error, stdout, stderr) => {
  if (error) {
        console.log(`error: ${error.message}`);
        return;
    }
    if (stderr) {
        console.log(`stderr: ${stderr}`);
        return;
    }
  console.log(stdout)
})

// using it in the shell

% node server.js

// should output this:

printed in python

This way you could traverse your XML file, change it and output it to the js/ts file, or save it as a file and just read that via your js/ts code.
