# types-aiobotocore-lambda — Type annotations for aiobotocore Lambda 3.9.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 1.7M/mo

## What it is and what it does

types-aiobotocore-lambda is a type stub package that adds static type annotations to aiobotocore's Lambda service client. It is generated from aiobotocore 3.9.0 using mypy-boto3-builder 8.12.0 and provides type hints for client methods, paginators, waiters, and service resource types. When installed, it enables IDEs and type checkers to validate your async AWS Lambda code without requiring explicit type annotations in your source.

The package works by providing `.pyi` stub files that describe the shape of aiobotocore's Lambda API. Once installed in your environment, mypy, pyright, VSCode Pylance, PyCharm, and other tools automatically use these stubs to offer code completion and catch type errors. It is designed as a development-only dependency and can be safely excluded from production using TYPE_CHECKING guards.

Use it for:

- Enable IDE autocompletion and type checking when writing async Lambda client code with aiobotocore.
- Catch type errors in Lambda API calls (invoke, create_function, update_function_code) before runtime.
- Provide explicit type annotations for LambdaClient, paginators, and waiters in mypy or pyright CI pipelines.
- Support code navigation and refactoring in PyCharm or VSCode by resolving Lambda service method signatures.
- Validate paginator and waiter usage patterns without manual type annotations.

## Worth the install?

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

Provides type annotations and IDE autocompletion for aiobotocore Lambda 3.9.0, enabling static type checking with mypy, pyright, and editor support in VSCode, PyCharm, Emacs, and Sublime Text.

Yes. This is a zero-friction, actively maintained type stub package with no known vulnerabilities, permissive licensing, and broad IDE/checker support. Install it if you use aiobotocore's Lambda service and want static type checking or IDE completion; it is purely a development aid and can be excluded from production builds.

## Install

pip install types-aiobotocore-lambda
uv add types-aiobotocore-lambda
poetry add types-aiobotocore-lambda

## Installing types-aiobotocore-lambda

Before you install: Low friction: single runtime dependency (typing-extensions), wheel-only distribution, and actively maintained with a recent release. Marked Production/Stable and supports Python 3.9 through 3.14.

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

Quickstart:

pip install types-aiobotocore-lambda

from aiobotocore.session import get_session
from types_aiobotocore_lambda import LambdaClient

session = get_session()
async with session.create_client("lambda") as client:
    client: LambdaClient
    # Type checking and IDE completion now available

Requires aiobotocore 3.9.0 to be installed separately; types-aiobotocore-lambda is stubs-only and does not provide runtime functionality.

Verify before relying:

- Whether PyCharm performance issues with Literal overloads (PY-40997) remain unresolved in current PyCharm versions.
- Whether the lite variant (types-aiobotocore-lite) is recommended over the full package for new projects.
