mypy-boto3-pca-connector-scep Type Annotations

Warnings

• breaking Support for Python 3.8 was removed in `mypy-boto3-builder` version 8.12.0. All generated `mypy-boto3-*` packages, including this one, now require Python >= 3.9.
  Fix: Upgrade your Python environment to 3.9 or newer.
• breaking The `mypy-boto3-builder` migrated to PEP 561 compliant packages in version 8.12.0. This primarily changes packaging internals but may affect projects with custom type-checking setups or older tool versions.
  Fix: Ensure your type-checking environment and tools are up-to-date and correctly configured to discover PEP 561 packages. Generally, this should work out-of-the-box with `pip` and modern `mypy`.
• breaking In `mypy-boto3-builder` version 8.9.0, there were breaking changes to TypeDef naming conventions. Packed method arguments now use shorter names (e.g., `CreateDistributionRequestRequestTypeDef` -> `CreateDistributionRequestTypeDef`), and conflicting 'Extra' postfixes were moved (e.g., `CreateDistributionExtraRequestTypeDef` -> `CreateDistributionRequestExtraTypeDef`). While the example is not for this service, similar changes could affect `pca-connector-scep` TypeDefs.
  Fix: Review your code for any explicit imports or usage of TypeDefs from the `mypy_boto3_pca_connector_scep.type_defs` module and update names according to the new conventions.
• gotcha This package provides *type annotations* for `boto3`. You must have `boto3` itself installed in your environment for your code to run correctly at runtime.
  Fix: Always install `boto3` alongside `mypy-boto3-pca-connector-scep` (e.g., `pip install boto3 mypy-boto3-pca-connector-scep`).
• gotcha PyCharm users might experience slow performance or high CPU usage due to `Literal` overloads. It is recommended to use `boto3-stubs-lite` (if available for this service) or disable PyCharm's built-in type checker and rely on `mypy` or `pyright` instead.
  Fix: Consider using `mypy-boto3-pca-connector-scep-lite` if available, or configure PyCharm to use external type checkers and disable its internal one.
• gotcha For optimal Pylint compatibility when using `TYPE_CHECKING` for conditional imports, Pylint might complain about undefined variables in the `else` block. To fix this, explicitly set the types to `object` in the non-type-checking branch.
  Fix: Implement conditional type assignments, e.g., `if TYPE_CHECKING: from mypy_boto3_pca_connector_scep.client import PrivateCAConnectorforSCEPClient else: PrivateCAConnectorforSCEPClient = object`.

Install

• pip install mypy-boto3-pca-connector-scep boto3 Install with pip

Imports

• PrivateCAConnectorforSCEPClient

  from mypy_boto3_pca_connector_scep.client import PrivateCAConnectorforSCEPClient

• Session

  from boto3.session import Session

  For explicit type hints, import Session directly from boto3.session and the client from the stubs package.

Quickstart

This quickstart demonstrates how to import and use the type-hinted `PrivateCAConnectorforSCEPClient` from `mypy-boto3-pca-connector-scep` with `boto3`. It includes conditional imports for `TYPE_CHECKING` to ensure the stubs are only used during type checking, avoiding runtime dependencies.

from typing import TYPE_CHECKING
import boto3
from boto3.session import Session

if TYPE_CHECKING:
    from mypy_boto3_pca_connector_scep.client import PrivateCAConnectorforSCEPClient

def get_pca_scep_client() -> PrivateCAConnectorforSCEPClient:
    """Initializes and returns a type-hinted AWS Private CA Connector for SCEP client."""
    session = Session(region_name="us-east-1")
    # In some IDEs or older configurations, explicit type annotation might be helpful:
    # client: PrivateCAConnectorforSCEPClient = session.client("pca-connector-scep")
    client = session.client("pca-connector-scep")
    return client

if __name__ == "__main__":
    client = get_pca_scep_client()
    try:
        # Example usage (replace with actual API call)
        response = client.list_connectors()
        print(f"Successfully listed {len(response.get('Connectors', []))} connectors.")
    except client.exceptions.ResourceNotFoundException as e:
        print(f"Resource not found: {e}")
    except Exception as e:
        print(f"An error occurred: {e}")
