types-babel

What it is and what it does

types-babel is a PEP 561 type stub package that provides type information for the babel internationalization library. It allows static type checkers—mypy, pyright, pytype, and PyCharm—to understand and validate code using babel's date formatting, number localization, and message translation functions. The stubs are sourced from the typeshed project and marked as partial, meaning some annotations may be incomplete.

The package is primarily useful for projects that depend on older versions of babel (pre-2.12.1) or that require strict type checking in environments where babel's native annotations are not yet available. Since babel 2.12.1, the upstream library includes its own type annotations, making this stub package redundant for newer installations. The package depends on types-pytz and types-setuptools for its own type information.

Use it for:

• Enable mypy or pyright type checking in a project using babel < 2.12.1 for date and number localization
• Validate internationalization code in legacy applications that cannot upgrade babel to a version with native type stubs
• Provide IDE autocomplete and type hints for babel functions in editors like PyCharm when using older babel versions
• Ensure type safety in continuous integration pipelines that enforce strict type checking on i18n-heavy codebases

Worth the install?

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

Provides type stubs for the babel package, enabling static type checkers like mypy and pyright to validate code that uses babel for internationalization and localization.

No, unless you are locked into babel < 2.12.1. For babel 2.12.1 and later, uninstall this package and rely on babel's native type annotations instead. The stub package is outdated (last updated 2023-07-20) and redundant for modern babel versions. If you must use an older babel, install it only as a development dependency for type checking.

Install

types-babel on PyPI

pip install types-babel

uv add types-babel

poetry add types-babel

Installing types-babel

Before you install

Low install friction with a pure-Python wheel distribution. Actively maintained as part of typeshed, though the package has not been updated since 2023-07-20 (over 1121 days ago). Note: babel itself has included native type annotations since version 2.12.1, making this stub package redundant for newer babel versions.

License in practice

Licensed under Apache-2.0 (permissive), allowing use in most commercial and open-source projects without significant restrictions.

Quickstart

pip install types-babel

# In your code, type checkers will now understand babel imports
from babel.dates import format_date
from datetime import date

result = format_date(date.today(), locale='en_US')

Only needed if using babel < 2.12.1; babel 2.12.1+ includes native type annotations, making this package unnecessary.

Verify before relying

• Whether the stub package remains compatible with recent babel versions beyond 2.12.1
• Coverage completeness of the partial stubs relative to current babel API surface
