Each package below has its own auto-generated reference documentation, regenerated independently on every upstream release.

- [**Pulumi SDK** (`pulumi`)](/docs/reference/pkg/python/pulumi/): the core Pulumi SDK for Python.
- [**Pulumi Policy SDK** (`pulumi_policy`)](/docs/reference/pkg/python/pulumi_policy/): for authoring policy packs for Pulumi Policies in Python.
- [**Pulumi ESC SDK** (`pulumi_esc_sdk`)](/docs/reference/pkg/python/pulumi_esc_sdk/): for programmatically interacting with Pulumi ESC (Environments, Secrets, and Configuration).

The reference for the Pulumi Terraform Bridge Python package has moved — see [Terraform on the Pulumi Registry](/registry/packages/terraform/api-docs/).
