Detecting whether your code is running on App Engine servers, or in development

For one of my projects running on Google App Engine, I'm using Google Analytics to track traffic, but I didn't want the tracking code showing up in my local development environment. Fortunately, detecting where your code is running is easy.

Take a look at this sample:

import os

try:
  is_dev = os.environ['SERVER_SOFTWARE'].startswith('Dev')
except:
  is_dev = False

is_prod = not(is_dev)

If the is_dev and is_prod variables are exposed to your templates, you can do something like this:

{% if is_prod %}
 {% include "analytics.html" %}
{% endif %}

Hope this helps!
