yarl — Yet Another URL Library

yarl is an immutable, RFC 3986-compliant URL parsing and manipulation library for Python 3. It provides the URL class with automatic percent-encoding/decoding, pathlib-style path operations, query-string helpers, and human-readable representations. The current release is 1.23.0, published March 2026. Releases ship frequently (multiple times per minor version) as part of the aio-libs ecosystem, closely tracking aiohttp.
