Setting Up Your Development Environment

To set up your environment for developing on Python 3:

  1. Install the latest release of Python 3.

    See Python 3 Runtime Environment for a list of the supported versions.

  2. Install and initialize the Cloud SDK. If you already have the Cloud SDK installed and initialized, run the gcloud components update command to update to the latest release.

    The Cloud SDK provides you the gcloud command-line tool for deploying and managing your apps.
