# mypy-boto3-forecast — Type annotations for boto3 ForecastService 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 255.4K/mo

## What it is and what it does

This package is a type-stub library that adds static type information to boto3's ForecastService client. It is generated from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, and Sublime Text. When installed, it enables IDE code completion and catches type errors at development time without requiring explicit type annotations in your code.

The package contains type definitions for the ForecastService client, paginators, and service-specific types. It is designed as a development-only dependency—you can conditionally import it using TYPE_CHECKING to avoid adding it to production dependencies. The library supports Python 3.9 through 3.14 and depends only on typing-extensions at runtime.

Use it for:

- Enable IDE autocomplete and type hints when writing boto3 ForecastService code in VSCode, PyCharm, or other supported editors.
- Run mypy or pyright type checking on code that uses boto3 ForecastService to catch type errors before runtime.
- Reduce development friction by avoiding manual type annotations for ForecastService client methods and responses.
- Integrate type checking into CI/CD pipelines for AWS Forecast workflows using standard Python type checkers.

## Worth the install?

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

Provides type annotations and IDE autocompletion for boto3's ForecastService client, enabling static type checking with mypy, pyright, and IDE support.

Yes. Install this if you use boto3's ForecastService and want static type checking or IDE autocompletion. It has low install friction, active maintenance, no security issues, and a permissive MIT license. The only caveat is PyCharm users may experience performance issues with Literal overloads—the documentation recommends boto3-stubs-lite as an alternative in that case.

## Install

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

## Installing mypy-boto3-forecast

Before you install: Low friction installation with a single runtime dependency (typing-extensions). Actively maintained as of 2026-06-22 with stable status.

License in practice: MIT license permits unrestricted use, modification, and distribution with minimal restrictions—suitable for any project type.

Quickstart:

pip install mypy-boto3-forecast

from boto3.session import Session
from mypy_boto3_forecast import ForecastServiceClient

client: ForecastServiceClient = Session().client("forecast")

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

Verify before relying:

- Whether type coverage includes all ForecastService operations and response types
- Performance impact when used with PyCharm (documentation mentions potential slowness with Literal overloads)
