Google App Engine revs up Python 3 support

One after another, the arguments against using Python 3 in production keep dropping away. Yesterday, Google consigned another one to oblivion: “But there’s no Python 3 support on Google App Engine!”

Well, guess what?

Google App Engine’s Flexible Environment, which scales apps based on demand, has launched support for Python 3.4 as a beta-test offering.

The runtimes for App Engine Flexible run as Docker containers, with the Dockerfiles available on GitHub. Developers can build the container locally, test their applications against it, then deploy the app alone to App Engine. It’s also possible to customize the runtime, upload it as a Docker container to App Engine, and run the app in conjunction with it.
