types-aiobotocore-stepfunctions

What it is and what it does

This package is a type stub library for aiobotocore's Step Functions (SFN) service, generated by mypy-boto3-builder. It provides complete type annotations and IDE-friendly overloads so that your editor and type checker can understand the shape and behavior of aiobotocore's SFN client, paginators, and related objects without requiring explicit type hints in your code.

You install it alongside aiobotocore, and it works transparently with VSCode (via Pylance), PyCharm, Emacs, Sublime Text, mypy, pyright, and other type-aware tools. The package is pure stubs—it adds no runtime behavior—and can be safely confined to development dependencies using TYPE_CHECKING guards if needed. It supports Python 3.9 through 3.14 and is actively maintained.

Use it for:

• Enable IDE autocomplete and inline documentation for aiobotocore Step Functions client methods without writing manual type annotations.
• Catch type errors in Step Functions API calls (e.g., wrong parameter names or types) during development with mypy or pyright.
• Provide paginator and waiter type hints for Step Functions list and describe operations.
• Support type-aware refactoring and navigation in IDEs when working with async Step Functions workflows.
• Keep type checking in CI/CD pipelines while avoiding runtime overhead by importing stubs only under TYPE_CHECKING.

Worth the install?

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

Provides type stubs and annotations for aiobotocore's Step Functions service, enabling IDE code completion and static type checking with mypy, pyright, and other tools.

Yes. This is a lightweight, actively maintained type stub with no security issues, permissive licensing, and low install friction. Install it if you use aiobotocore's Step Functions service and want IDE support and static type checking; it is especially valuable in teams using mypy or pyright. If you experience PyCharm performance issues, the documentation suggests switching to the lite variant.

Install

types-aiobotocore-stepfunctions on PyPI

pip install types-aiobotocore-stepfunctions

uv add types-aiobotocore-stepfunctions

poetry add types-aiobotocore-stepfunctions

Installing types-aiobotocore-stepfunctions

Before you install

Low install friction with a single lightweight runtime dependency (typing-extensions). Actively maintained with a recent release (12 days old) and stable repository status.

License in practice

MIT license permits unrestricted use, modification, and distribution with minimal obligations—safe for both open-source and commercial projects.

Quickstart

pip install types-aiobotocore-stepfunctions

from aiobotocore.session import get_session
from types_aiobotocore_stepfunctions import SFNClient

session = get_session()
async with session.create_client("stepfunctions") as client:
    client: SFNClient  # Type checker now understands client methods

Requires Python 3.9 or later; aiobotocore must be installed separately as a runtime dependency.

Verify before relying

• Performance impact in PyCharm with Literal overloads (documentation mentions issue PY-40997 but does not quantify severity).
• Whether the lite variant (types-aiobotocore-lite) is necessary for typical projects or only for performance-constrained environments.
