rfc3986

rfc3986 is a Python implementation of RFC 3986 including validation and authority parsing. This module also supports RFC 6874, which adds support for zone identifiers to IPv6 Addresses. It provides APIs for parsing, validating, and building URIs, with convenience methods for `urllib.parse` compatibility. The current version is 2.0.0, released in January 2022, and the project appears to be actively maintained.
