A port of Ruby on Rails inflector to Python
Decision gist · record as of 2026-08-14
Yes, for stable string transformation tasks. The package is mature, dependency-free, permissively licensed, and has no known vulnerabilities. Its abandonment is not a blocker for a stable utility library, but you should verify that its pluralization rules match your specific English vocabulary needs before relying on it for critical naming logic.AI-flagged interpretation of the facts on this page — verify before relying

inflection.camelize('snake_case')- Whether the package handles edge cases and irregular plurals correctly for modern English usage.
- Whether abandonment affects compatibility with current Python versions beyond the stated support range.
What it is and what it does
Inflection is a Python port of Ruby on Rails' inflector library for English string transformations. It provides functions to convert between singular and plural forms of English words, and to transform strings between naming conventions—specifically between CamelCase and underscored (snake_case) formats. The library has no runtime dependencies and installs as a pure Python wheel.
The package is useful for code generation, API design, and any context where you need to programmatically convert between naming conventions or handle English word inflection. It was last released in August 2020 and is no longer actively maintained, though the repository remains archived but accessible.
Use it for
- Convert database column names from snake_case to CamelCase for API responses or ORM mappings.
- Generate Python variable and function names from user-provided strings in configuration or templates.
- Transform class names to plural forms for collection endpoints or table names in database schemas.
- Normalize naming conventions when integrating code from different sources or style guides.
