I’m using dependency_injector to manage DI. I don’t understand how to release my resources using this library.

I found shutdown_resources method but have no idea how to use it properly.

Example:

class Resource:
    """Resource example."""

    def __init__(self):
        """."""

        # Initialize session

    def close(self):
        """Release resources."""

        # Close session

class ApplicationContainer(DeclarativeContainer):
    """Application container."""

    resource: Singleton[Resource] = Singleton[Resource](Resource)


container = ApplicationContainer()
# Do something
container.shutdown_resources() # Call close method here
