# types-tornado — Typing stubs for tornado

License: permissive · Maintenance: active · Downloads: 76.8K/mo

## What it is and what it does

types-tornado is a type stub package that provides type information for the tornado package to static type checkers. It allows tools like mypy, PyCharm, and pytype to understand tornado code and catch type errors at development time. The stubs are maintained as part of the typeshed project.

The package description explicitly notes that tornado has included type annotations since version 6.0, and recommends uninstalling types-tornado if you use that version or newer. The package has not been updated since 2021-08-27.

Use it for:

- Type-checking code that depends on tornado versions before 6.0.
- Enabling IDE autocompletion in projects using older tornado releases.
- Validating tornado usage in codebases where upgrading tornado is not immediately feasible.

## Worth the install?

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

Provides PEP 561 type stubs for tornado, enabling static type checkers like mypy and PyCharm to validate code using tornado.

No, unless locked into tornado versions before 6.0. For tornado 6.0 or later, tornado's built-in type annotations make this package redundant. The package has not been updated since 2021-08-27, and its own description recommends uninstalling it if using tornado 6.0 or newer.

## Install

pip install types-tornado
uv add types-tornado
poetry add types-tornado

## Installing types-tornado

Before you install: Low install friction as a pure stub package with no runtime dependencies. However, the package has not been updated since 2021-08-27, and the description notes that tornado has included type annotations since version 6.0.

License in practice: Licensed under Apache-2.0, a permissive open-source license allowing use, modification, and distribution with minimal restrictions.

Quickstart:

pip install types-tornado==5.1.1

import tornado.web
# Type checkers can now validate tornado code

Verify before relying:

- Whether tornado 6.0+ built-in type annotations fully replace types-tornado for all use cases.
- Current compatibility with recent tornado versions and modern type checkers.
- Whether this package remains necessary for any active tornado deployments.
