Whilst developing I want to handle some things slight differently than I will when I eventually upload to the Google servers.

Is there a quick test that I can do to

See: https://cloud.google.com/appengine/docs/python/how-requests-are-handled#Python_The_environment

The following environment variables are part of the CGI standard, with special behavior in App Engine: SERVER_SOFTWARE:

In the development web server, this value is "Development/X.Y" where "X.Y" is the version of the runtime.

When running on App Engine, this value is "Google App Engine/X.Y.Z".
