title: How to link HTML page with python
body: <p>I have a form in an HTML page that reads input from a user (string x), and I have my python script that uses this variable.</p>
  
  <p>What is the easiest way to fetch this variable from the HTML page by the python script (.py) and return the result - which should also be a string -  to show it in the HTML page again?</p>
