Finally, we shall see how dynamic content can be interpolated

• Edit the website's second HTML page, enter {{mycontent}} (this literal text!) as content somewhere inside the main content block:

  <div class="content-box main-content">
  ...
    {{mycontent}}
  ...

• Now modify the server.py code (the second_page function) to take in the desired value as a request parameter and pass it to the mycontent template variable, e.g.:

  def second_page():
    render_template("second.html", mycontent=request.args.get("mycontent", "<not specified>"))

• Open the endpoint URL and pass the mycontent value as a GET URL parameter (e.g., ?parameter=value) and see if the content changes dynamically after the request!
• This is a template engine called Jinja, seamlessly integrated with Flask. More about this: next time!
