Type Annotations for boto3 SecurityLake

Warnings

• breaking Python 3.8 support was removed with `mypy-boto3-builder` version 8.12.0. This `mypy-boto3-securitylake` package (version 1.42.3) requires Python 3.9 or newer.
  Fix: Upgrade your Python environment to 3.9 or newer.
• breaking Beginning with `mypy-boto3-builder` version 8.9.0, there were breaking changes to TypeDef naming conventions, including shorter names for packed method arguments and moving the `Extra` postfix. This might require updating existing type annotations in your code.
  Fix: Review and update `TypeDef` names in your codebase according to the new conventions.
• gotcha This package provides type stubs for `boto3`. You must also install `boto3` itself for your code to run, as `mypy-boto3-securitylake` only provides the type definitions, not the AWS SDK implementation.
  Fix: Ensure `boto3` is installed alongside `mypy-boto3-securitylake` (e.g., `pip install mypy-boto3-securitylake boto3`).
• gotcha To ensure accurate type hints and autocompletion, keep `mypy-boto3-securitylake` and `boto3` versions synchronized. Significant version mismatches can lead to incorrect type information or missing definitions.
  Fix: Regularly update both packages, ideally together, to their latest compatible versions.
• gotcha Some IDEs (e.g., PyCharm) may experience slow performance or high CPU usage when processing the extensive type information from `boto3-stubs` (the umbrella project for `mypy-boto3-*` packages).
  Fix: Consider using `boto3-stubs-lite` if the full stubs are too demanding, or configure your IDE to use external type checkers like `mypy` or `pyright` instead of its built-in type checker.
• gotcha For optimal autocompletion and type inference in IDEs like VSCode and PyCharm, it is often beneficial to explicitly annotate the type of `boto3.client` and `boto3.resource` calls with the corresponding `mypy_boto3_securitylake` client or resource type.
  Fix: Add explicit type hints, e.g., `client: SecurityLakeClient = boto3.client('securitylake')`.

Install

• pip install mypy-boto3-securitylake boto3 Install library and boto3

Imports

• SecurityLakeClient

  from mypy_boto3_securitylake.client import SecurityLakeClient

  For type-hinting the SecurityLake service client.
• ListDataLakesResponseTypeDef

  from mypy_boto3_securitylake.type_defs import ListDataLakesResponseTypeDef

  For type-hinting responses from SecurityLake API calls, e.g., `list_data_lakes()`.

Quickstart

Demonstrates how to import and use the `SecurityLakeClient` for type-hinted interaction with AWS SecurityLake, including fetching data lakes and their details. Explicit type annotations are shown for clarity and improved IDE experience.

import boto3
from mypy_boto3_securitylake.client import SecurityLakeClient
from mypy_boto3_securitylake.type_defs import ListDataLakesResponseTypeDef
import os

def get_securitylake_data_lakes() -> ListDataLakesResponseTypeDef:
    # It's recommended to explicitly type the client for best IDE support
    client: SecurityLakeClient = boto3.client(
        "securitylake", 
        region_name=os.environ.get('AWS_REGION', 'us-east-1'),
        aws_access_key_id=os.environ.get('AWS_ACCESS_KEY_ID', ''),
        aws_secret_access_key=os.environ.get('AWS_SECRET_ACCESS_KEY', '')
    )
    response = client.list_data_lakes()
    return response

if __name__ == "__main__":
    data_lakes = get_securitylake_data_lakes()
    print(f"Found {len(data_lakes.get('DataLakes', []))} data lakes:")
    for dl in data_lakes.get('DataLakes', []):
        print(f"- Region: {dl['Region']}, ARN: {dl['DataLakeArn']}")
