# mypy-boto3-s3files — Type annotations for boto3 S3Files 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 120.5K/mo

## What it is and what it does

This package is a type-stub library that adds static type information for boto3's S3Files service. It is generated automatically from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with mypy, pyright, VSCode, PyCharm, Emacs, Sublime Text, and other tools that support Python type hints.

When installed, it enables IDE code completion and type checking for S3Files client operations without requiring explicit type annotations in your code. The package is stub-only (contains no runtime code beyond type definitions) and can be safely used in development environments or guarded behind TYPE_CHECKING blocks to avoid production dependencies.

Use it for:

- Enable IDE autocompletion and inline documentation for boto3 S3Files API calls in VSCode or PyCharm.
- Run mypy or pyright type checking on boto3 code to catch type errors before runtime.
- Provide explicit type annotations for S3FilesClient, paginators, and service resources in larger codebases.
- Integrate type hints into CI/CD pipelines to enforce static type safety on AWS SDK usage.
- Reduce development friction by avoiding manual type annotation of boto3 responses and parameters.

## Worth the install?

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

Provides type annotations and IDE autocompletion support for boto3's S3Files service, enabling static type checking with mypy, pyright, and compatible editors.

Yes—if you use boto3's S3Files service and want IDE autocompletion or static type checking. Install friction is minimal, the package is actively maintained with no vulnerabilities, and MIT licensing poses no restrictions. Install as a dev dependency or behind TYPE_CHECKING to avoid production overhead.

## Install

pip install mypy-boto3-s3files
uv add mypy-boto3-s3files
poetry add mypy-boto3-s3files

## Installing mypy-boto3-s3files

Before you install: Low install friction with a single lightweight runtime dependency (typing-extensions). Package is actively maintained with recent releases and no known vulnerabilities.

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

Quickstart:

pip install mypy-boto3-s3files

from boto3.session import Session
from mypy_boto3_s3files import S3FilesClient

client: S3FilesClient = Session().client("s3files")

Requires Python 3.9 or later. Type checking requires a compatible tool (mypy, pyright, or IDE with type support).

Verify before relying:

- Performance impact in PyCharm; documentation mentions potential slowness but does not quantify it.
- Whether the lite variant (boto3-stubs-lite) is recommended for production use over this package.
