mypy-boto3-dynamodb

What it is and what it does

This package is a type stub library that adds complete type annotations to boto3's DynamoDB service. It works by providing type hints for all DynamoDB client methods, paginators, waiters, and service resources, allowing your IDE and type checker to understand what arguments each function accepts and what it returns.

When installed, it enables static type checking with mypy or pyright, IDE autocomplete in VSCode, PyCharm, Emacs, and Sublime Text, and catches type errors before runtime. The stubs are generated automatically from boto3 1.43.64 using mypy-boto3-builder 8.12.0, so they stay synchronized with the AWS SDK. You write boto3 code normally—the stubs work transparently in the background to provide type information.

Use it for:

• Enable IDE autocompletion and type hints when writing DynamoDB queries in VSCode or PyCharm.
• Catch type errors in boto3 DynamoDB calls during static analysis with mypy or pyright before deployment.
• Document DynamoDB client method signatures and return types for team members reviewing code.
• Reduce runtime errors by catching incorrect argument types or missing required parameters at development time.
• Integrate type checking into CI/CD pipelines to enforce type safety on all DynamoDB operations.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides type annotations and IDE autocompletion for boto3 DynamoDB operations, enabling static type checking with mypy, pyright, and other tools.

Yes. This is a low-friction, actively maintained type stub package with no security vulnerabilities and permissive MIT licensing. Install it if you use boto3 DynamoDB and want IDE autocompletion or static type checking. The only caveat is potential performance issues with certain IDEs on large codebases—consult the documentation if you experience slowness.

Install

mypy-boto3-dynamodb on PyPI

pip install mypy-boto3-dynamodb

uv add mypy-boto3-dynamodb

poetry add mypy-boto3-dynamodb

Installing mypy-boto3-dynamodb

Before you install

Low friction install with a single lightweight runtime dependency (typing-extensions). Actively maintained with recent releases; last commit on 2026-06-22 and released 10 days ago.

License in practice

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

Quickstart

pip install mypy-boto3-dynamodb

from mypy_boto3_dynamodb import DynamoDBClient
import boto3

client: DynamoDBClient = boto3.client('dynamodb')

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

Verify before relying

• Whether performance impact in PyCharm is acceptable for your codebase size (docs mention slow Literal overload handling).
• Whether a lite variant is available and would be a better fit for your memory or IDE response requirements.
