Yes, if you need functional programming utilities beyond the standard library. Low install friction, active maintenance, MIT license, no known vulnerabilities, and top-1000 popularity make it a safe choice. Install only if you have a specific need for the additional functools it provides—it's a specialized library, not a general dependency.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Low install friction with a single lightweight dependency (more_itertools).

What it is and what it does
jaraco.functools extends Python's standard library functools module with additional decorators and higher-order function utilities. It provides functional programming tools in the same spirit as the standard library, designed to fill common gaps in the stdlib's functools offerings.
The package depends only on more_itertools and targets modern Python versions (3.10+). It is actively maintained with stable production status, making it suitable for projects that need additional functional programming patterns beyond what the standard library provides.
Use it for
- Extend stdlib functools with additional decorators when standard library utilities are insufficient for your functional programming needs.
- Build function composition and higher-order function patterns in projects that rely heavily on functional programming techniques.
- Add specialized memoization or caching decorators beyond functools.lru_cache for specific use cases.
- Simplify decorator chaining and function wrapping in utility-heavy codebases.
