## What it is
Babel is the standard Python library for internationalization and localization, built on CLDR data. It provides locale-aware date, number, and currency formatting plus gettext-based message catalog tooling.

## Use cases
- translate a python web app into multiple languages
- format dates and numbers per user locale
- extract translatable strings from python code
- compile gettext .po message catalogs
- localize currency and decimal formatting
- handle timezones and locale-aware calendars

## When to choose
- you need mature, CLDR-backed i18n in Python
- your web framework (Flask, Pyramid, Django-adjacent) needs locale formatting
- you want gettext workflow tooling in Python

## When to avoid
- you need frontend/browser i18n (use Intl or a JS library)
- you need machine translation or translation management services
- your project is not Python

## Facets
- artifact type: library
- maturity: stable
- function: internationalization, templating, date-time
- domain: web-development, developer-tools
- platform: python, cross-platform
- tags: i18n, l10n, gettext, cldr, locale-formatting, message-catalogs, translation, localization
