mypy-boto3-iam

What it is and what it does

mypy-boto3-iam is a type stub package that adds complete type annotations for the boto3 IAM service. It enables static type checkers like mypy and pyright, as well as IDEs like VSCode, PyCharm, Emacs, and Sublime Text, to provide accurate code completion and catch type errors when working with AWS IAM through boto3.

The package is generated from boto3 1.43.70 using mypy-boto3-builder 8.12.0 and provides annotations for IAM clients, paginators, waiters, service resources, and type definitions. It has a single runtime dependency (typing-extensions) and supports Python 3.9 through 3.14, making it lightweight to install and compatible with modern Python environments.

Use it for:

• Enable IDE autocompletion and type hints when writing boto3 IAM code in VSCode with Pylance or PyCharm.
• Run mypy or pyright type checking on IAM-related boto3 code to catch errors before runtime.
• Provide explicit type annotations for IAM client objects, paginators, and waiters in production code.
• Use in Emacs or Sublime Text with LSP-pyright for real-time type checking and code completion.
• Validate IAM API calls and resource operations statically without executing code.

Worth the install?

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

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

Yes. This is a low-friction, actively maintained type stub package with no known vulnerabilities, permissive licensing, and broad IDE support. Install it if you use boto3 for IAM and want type checking and autocompletion. Note that PyCharm users may experience performance issues with the full version and should consider boto3-stubs-lite as an alternative.

Install

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

Quickstart

pip install mypy-boto3-iam

from boto3.session import Session
from mypy_boto3_iam import IAMClient

client: IAMClient = Session().client("iam")

Requires Python 3.9 or later and boto3 1.43.70 to be installed separately.

Verify before relying

• Whether PyCharm performance issues mentioned in the description (PY-40997) remain unresolved or have been addressed.
• Whether the lite variant (boto3-stubs-lite) offers meaningfully better IDE performance than this full version.
