AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Inflection transforms English words and strings: singularizes and pluralizes words, and converts between CamelCase and underscored naming conventions.

Low install friction with no runtime dependencies. However, the package is abandoned—last release was 2020-08-22, over 2182 days ago, with no recent commits.

Licensed under MIT (permissive), allowing free use, modification, and distribution with minimal restrictions.

Usage

pip install inflection==0.5.1

import inflection
print(inflection.pluralize('word'))
print(inflection.camelize('hello_world'))

Requires Python 3.5 or later.

Verdict: Inflection is a lightweight, dependency-free string transformation library with permissive MIT licensing and no known vulnerabilities. Its abandonment since 2020 and lack of maintenance pose a long-term risk; use only if its specific inflection rules match your needs and you can maintain a fork if required.

Needs verification

Whether inflection's English pluralization and singularization rules remain accurate for contemporary usage.
Whether the package's behavior on Python 3.9+ has been validated by users post-2020.
