Yes, if you must work with Java PropertyResourceBundle files or are porting from Java. The package is low-friction to install and has no known vulnerabilities. However, it is dormant—do not expect active maintenance or bug fixes. For new Python projects, use Python's standard gettext module instead. The package is suitable for legacy integration or one-time migration tasks.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Installation is straightforward with low friction—a pure Python wheel with only importlib-metadata as a runtime dependency.
- The package is dormant (last release April 2024, last commit July 2024) but not archived, so it remains available; expect no active maintenance.

What it is and what it does
ResourceBundle is a bridge for Python developers who need to work with Java PropertyResourceBundle files—the same key-value format Java uses for i18n. It loads locale-specific resource bundles, retrieves translated strings by key, and falls back through parent bundles (e.g., from en_US to en to a default) when a key is not found. The package also includes a converter to migrate PropertyResourceBundle files to Python's standard gettext format.
The package is explicitly not the Pythonic way to do internationalization; the author recommends using Python's built-in gettext module for new projects. ResourceBundle is intended for porting existing Java applications to Python or for teams that must maintain compatibility with Java resource files. It has a single runtime dependency (importlib-metadata) and supports Python 3.5 through 3.13.
Use it for
- Porting a Java application to Python while preserving existing PropertyResourceBundle translation files.
- Loading locale-specific strings from .properties files in a Python application that originated from Java.
- Converting Java ResourceBundle files to gettext .po files as a one-time migration step.
- Maintaining a shared resource bundle format across Java and Python codebases in a polyglot team.
- Quick prototyping when you already have Java .properties files and need them available in Python immediately.
