How do I include dynamic page content in a template?

I need to include dynamic page content in my template. Let's say I have a left pane that dynamically passes data through a view. Now I have to include this left panel in all of my pages, but I don't want to duplicate code for all pages. Is there a way I can write one script and include it in all of my templates to display the left pane on all my pages?

Thanks in advance.

What you are trying to achieve is directly supported in pretty much every templating language I know of. I would highly recommend using one of the many good Python options:

If you've used Genshi (the default templating language in TurboGears web app), what you want to do is something like this: 



<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:py="http://genshi.edgewall.org/"
      xmlns:xi="http://www.w3.org/2001/XInclude"
      py:strip="">
  <xi:include href="header.html" />
  <xi:include href="sidebar.html" />
  <xi:include href="footer.html" />

  <!-- The rest of your page goes here -->
<html>

header.html

, sidebar.html

and footer.html

only needs to be defined once and reused on any other page.
