# mypy-boto3-securitylake — Type annotations for boto3 SecurityLake 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 243.4K/mo

## What it is and what it does

This package is a type-stub library that adds static type information to boto3's SecurityLake service client. It is generated from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with mypy, pyright, VSCode (Pylance), PyCharm, Emacs, and Sublime Text to provide IDE code completion and type checking without requiring manual type annotations in your code.

The package contains type definitions for SecurityLakeClient, paginators, waiters, and service-specific data types. It is designed to be installed alongside boto3 and requires only typing-extensions as a runtime dependency. The documentation suggests using TYPE_CHECKING guards to avoid a production dependency, though the package itself is lightweight and poses minimal overhead.

Use it for:

- Enable IDE autocomplete and type hints when writing boto3 SecurityLake client code in VSCode or PyCharm.
- Run mypy or pyright static type checking on code that calls boto3 SecurityLake without writing explicit type annotations.
- Catch SecurityLake API usage errors (wrong argument types, missing required fields) at development time rather than runtime.
- Generate paginator and waiter type hints for SecurityLake operations like GetDataLakeSources and ListSubscribers.
- Integrate boto3 SecurityLake type checking into CI/CD pipelines using mypy or pyright.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type annotations and IDE autocompletion support for boto3's SecurityLake service, enabling static type checking with mypy, pyright, and editor tools.

Yes, if you use boto3's SecurityLake service and want static type checking or IDE autocomplete. Install friction is negligible (single pure-Python dependency), maintenance is active, and the MIT license carries no restrictions. No known vulnerabilities. The only caveat is PyCharm performance with full boto3-stubs; the documentation recommends boto3-stubs-lite as a workaround if you experience slowness.

## Install

pip install mypy-boto3-securitylake
uv add mypy-boto3-securitylake
poetry add mypy-boto3-securitylake

## Installing mypy-boto3-securitylake

Before you install: Low friction—a pure-Python wheel with a single lightweight runtime dependency (typing-extensions). Active maintenance with recent releases; last commit 2026-06-22.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects.

Quickstart:

pip install mypy-boto3-securitylake

from boto3.session import Session
from mypy_boto3_securitylake import SecurityLakeClient

client: SecurityLakeClient = Session().client("securitylake")

Requires Python 3.9 or later; boto3 must be installed separately in your environment.

Verify before relying:

- Performance impact in PyCharm with full boto3-stubs (documentation warns of slowness with Literal overloads; lite variant recommended as workaround).
- Whether the package is intended for development-only use (TYPE_CHECKING pattern suggested in docs but not enforced).
