mypy-boto3-pca-connector-ad Type Annotations for AWS PcaConnectorAd Service

Warnings

• breaking As of `mypy-boto3-builder` version 8.12.0 (which generates `mypy-boto3-pca-connector-ad` 1.42.3), support for Python 3.8 has been removed for all generated packages.
  Fix: Upgrade to Python 3.9 or higher. The PyPI metadata for this package explicitly requires `Python >=3.9`.
• breaking Starting with `mypy-boto3-builder` 8.9.0, there were breaking changes to `TypeDef` naming conventions. For example, `CreateDistributionRequestRequestTypeDef` became `CreateDistributionRequestTypeDef`, and `Extra` postfixes moved (`CreateDistributionExtraRequestTypeDef` to `CreateDistributionRequestExtraTypeDef`).
  Fix: Update explicit `TypeDef` imports and usage in your code to match the new naming conventions.
• gotcha `mypy-boto3-builder` 8.12.0 migrated all generated packages to PEP 561. While this improves standard compatibility, users with highly customized `mypy` configurations or build systems should be aware of potential impacts on how stubs are discovered.
  Fix: Verify that your `mypy` configuration and build tooling correctly discover PEP 561-compliant stub packages. Most standard setups should work without issues.
• gotcha While `mypy-boto3` aims for implicit type discovery, some IDEs (especially VSCode without specific `mypy` integration) or specific configurations (like `boto3-stubs-lite`) might require explicit type annotations for `boto3.Session().client()` and similar calls to provide full autocompletion and static analysis.
  Fix: Add explicit type annotations, e.g., `client: PcaConnectorAdClient = session.client("pca-connector-ad")`, to ensure consistent type checking across different environments and tools.
• gotcha When using `typing.TYPE_CHECKING` guards to conditionally import type stubs (e.g., for Pylint compatibility), Pylint might report 'undefined variable' errors for the types within the runtime block.
  Fix: To resolve Pylint complaints, set the stub types to `object` in the non-`TYPE_CHECKING` branch: `if TYPE_CHECKING: from mypy_boto3_ec2 import EC2Client else: EC2Client = object`.

Quickstart

This quickstart demonstrates how to initialize a `PcaConnectorAdClient` with type annotations and make a basic API call, `list_connectors`. It includes explicit type hints for improved static analysis and a `try-except` block to handle potential authentication or permission errors gracefully, common when running AWS SDK examples without proper setup.

# The TYPE_CHECKING block is for type checkers and won't be executed at runtime.
# It's good practice for clarity and compatibility with various tooling setups.
