Object-oriented paths
Decision gist · record as of 2026-08-14
Yes. Zero runtime dependencies, permissive license, active maintenance, and no known vulnerabilities make it a low-risk addition. Install if you frequently work with nested data and want cleaner, more composable access patterns than bracket chaining.AI-flagged interpretation of the facts on this page — verify before relying

What it is and what it does
Pathable is a small library that wraps nested data structures (dicts, lists, and other subscriptable objects) in path objects, letting you express deep lookups as single, reusable objects and navigate them with familiar `/` syntax. Instead of writing `data["parts"]["part2"]["name"]`, you write `(root / "parts" / "part2" / "name").read_value()`, which reads more naturally and lets you build and pass around partial paths.
The library offers both safe and strict access modes: `get()` returns a default for missing keys, `exists()` checks membership, and `//` raises KeyError if a segment is missing. It includes a per-instance LRU cache for repeated reads of the same tree, and supports custom accessor backends for different data sources (filesystem paths included). The API is chainable and Pythonic, designed for readable, incremental path construction.
Use it for
- Extract values from deeply nested JSON or YAML configs without intermediate variable assignments.
- Build and pass around partial paths to nested data as first-class objects in APIs.
- Safely probe optional nested structures with `exists()` or `get()` before reading.
- Traverse filesystem paths using the same path-like API as data lookups.
- Iterate over children of a nested container as path objects for recursive processing.
