-This pattern also helps you easily execute jobs in different environments without code changes. In this example, we dynamically defined a code location based on the deployment in [`definitions.py`](https://github.com/dagster-io/dagster/blob/master/examples/project_fully_featured/project_fully_featured/\__init\_\_.py) and can keep all code the same across testing, local development, staging, and production.
