types-futures

What it is and what it does

types-futures is a PEP 561 type stub package that provides type information for the standard library's futures module. It allows static type checkers—mypy, PyCharm, pytype, and similar tools—to understand the types and signatures of futures classes and functions when analyzing your code. The stubs are maintained as part of the typeshed project and are generated from its repository.

This package contains no runtime code; it exists solely to improve the type-checking experience. If you use a type checker and work with concurrent.futures or the futures package, installing this stub package will enable your checker to catch type errors and provide better IDE autocompletion. It has no runtime dependencies and installs as a lightweight wheel.

Use it for:

• Enable mypy or pyright to type-check code that uses ThreadPoolExecutor or ProcessPoolExecutor
• Get IDE autocompletion and type hints for futures module classes in development environments
• Validate callback signatures and return types in concurrent.futures workflows
• Ensure type safety in async or concurrent code before runtime execution

Worth the install?

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

Provides type stubs for the futures package, enabling static type checkers like mypy and PyCharm to understand and validate code using futures.

Yes, if you use a static type checker with code that imports from futures or concurrent.futures. It is a lightweight, permissive-licensed stub package with no dependencies and active upstream maintenance. Install it as part of your development environment to catch type errors early. If you do not use type checking, it provides no value.

Install

types-futures on PyPI

pip install types-futures

uv add types-futures

poetry add types-futures

Installing types-futures

Before you install

Low install friction with a pure-Python wheel distribution. Maintenance is active with recent repository activity, though the package itself has not been released since 2022-01-27.

License in practice

Licensed under Apache-2.0, a permissive license that allows use, modification, and distribution with minimal restrictions—suitable for both open-source and proprietary projects.

Quickstart

pip install types-futures

# Then use in your code with a type checker:
from concurrent.futures import ThreadPoolExecutor

executor = ThreadPoolExecutor(max_workers=2)
# Type checker now understands ThreadPoolExecutor's interface

Verify before relying

• Whether this stub package is still synchronized with the current futures API or if newer versions exist elsewhere
• Compatibility with modern type checkers and their evolving stub resolution mechanisms
