Decision gist · record as of 2026-08-14
No—the package is explicitly deprecated. The maintainers recommend switching to roman-numerals instead. Install only if you are maintaining legacy code that already depends on roman-numerals-py; for new projects, use the recommended replacement.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low friction installation as a pure Python wheel.
- Active maintenance with recent releases, though the package summary notes it is deprecated in favor of roman-numerals.

What it is and what it does
roman-numerals-py is a utility for bidirectional conversion between integers and Roman numerals. It lets you create a RomanNumeral object from an integer (e.g., 16 becomes 'XVI') and parse Roman numeral strings back into comparable objects. The package is a pure Python implementation with no compiled dependencies, making it straightforward to install and use.
However, the package summary explicitly states it is deprecated and recommends switching to roman-numerals instead. This means you should treat it as a legacy option; if you are starting a new project, the maintainers suggest using the replacement package. For existing code or specific compatibility needs, it remains functional and actively maintained, but migration is encouraged.
Use it for
- Convert integers to Roman numeral strings for display in historical or formal documents.
- Parse user-supplied Roman numeral input and validate or compare it against numeric values.
- Generate Roman numerals for outline numbering, clock faces, or other traditional formatting.
- Educational projects teaching numeral systems or number representation.
