Yes, if you work with crystal structures and need fast symmetry analysis. The package is actively maintained, permissively licensed, has no known vulnerabilities, and integrates well with popular materials-science libraries via optional extras. Medium install friction is typical for compiled scientific packages and not a barrier.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; pre-built wheels available for common platforms (x86_64, ARM64, macOS, Linux, Windows).
- Medium install friction due to compiled wheels; the package is actively maintained with a recent release (32 days old) and supports current Python versions (3.10–3.14).
- Requires only typing-extensions as a runtime dependency.

What it is and what it does
Moyopy wraps Moyo, a fast and robust crystal symmetry finder, into a Python interface for analyzing crystallographic structures. It identifies symmetry operations and space groups in crystal lattices, making it useful for materials science and computational chemistry workflows that need to understand or exploit crystal symmetries.
The package is in Beta status and actively maintained. It supports Python 3.10 through 3.14 with pre-built wheels for major platforms, keeping install friction moderate. Optional extras allow conversion of structures to Pymatgen or ASE formats for integration with broader materials-science pipelines.
Use it for
- Identify space groups and symmetry operations in crystal structures for materials discovery workflows.
- Validate or normalize crystallographic data by detecting and applying symmetry constraints.
- Convert crystal structures to Pymatgen or ASE objects for downstream analysis or visualization.
- Accelerate high-throughput computational materials screening by leveraging fast symmetry detection.
- Analyze symmetry properties in computational chemistry simulations or density-functional-theory results.
