mypy-boto3-arc-region-switch

What it is and what it does

This package is a type-stub library generated from boto3's ARCRegionswitch service definition. It provides complete type annotations for the service's client, paginators, waiters, and type definitions, allowing static type checkers and IDEs to understand boto3 code without runtime overhead.

It works by installing alongside boto3 and providing `.pyi` stub files that describe the service's API surface. Once installed, tools like mypy, pyright, VSCode Pylance, PyCharm, and Emacs can offer accurate code completion and catch type errors before runtime. The package is generated automatically from boto3 1.43.54 using mypy-boto3-builder 8.12.0, and can be used standalone or as part of the broader boto3-stubs ecosystem.

Use it for:

• Enable IDE autocomplete and inline documentation when writing boto3 ARCRegionswitch client code in VSCode or PyCharm.
• Run mypy or pyright in CI/CD to catch incorrect boto3 API calls and argument types before deployment.
• Reduce runtime errors by catching typos in service method names and parameter types during development.
• Provide explicit type hints for ARCRegionswitch clients, paginators, and waiters in type-checked Python projects.
• Support linting and type checking in Emacs or Sublime Text via LSP and pyright integration.

Worth the install?

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

Provides type annotations for boto3's ARCRegionswitch service, enabling IDE autocomplete, type checking with mypy and pyright, and static analysis across multiple editors.

Yes—if you use boto3's ARCRegionswitch service and want static type checking or IDE autocomplete. Install friction is minimal, maintenance is active, and the MIT license poses no restrictions. Skip only if you do not use this specific service or prefer dynamic typing without IDE support.

Install

mypy-boto3-arc-region-switch on PyPI

pip install mypy-boto3-arc-region-switch

uv add mypy-boto3-arc-region-switch

poetry add mypy-boto3-arc-region-switch

Installing mypy-boto3-arc-region-switch

Before you install

Low friction install with a single lightweight runtime dependency (typing-extensions). Active maintenance with recent releases; last commit 2026-06-22 and version released 2026-07-22.

License in practice

MIT license permits unrestricted use, modification, and distribution with minimal restrictions—suitable for both open-source and proprietary projects.

Quickstart

pip install mypy-boto3-arc-region-switch

from boto3.session import Session
from mypy_boto3_arc_region_switch import ARCRegionswitchClient

client: ARCRegionswitchClient = Session().client("arc-region-switch")

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

Verify before relying

• Whether performance impact on PyCharm is acceptable for your project size (docs mention potential slowness with Literal overloads).
• Whether the generated stubs remain synchronized with boto3 ARCRegionswitch service updates beyond the 1.43.54 version.
