urlsplit

urlsplit is a function in Python's standard library (urllib.parse) that breaks a URL into five components: scheme, netloc, path, query, and fragment. It returns a SplitResult named tuple with attributes scheme, netloc, path, query, and fragment. The function provides a lightweight alternative to urlparse when you do not need a separate params component that can appear in the path.

Usage typically involves parsing a URL and optionally reconstructing it. For example, from urllib.parse import urlsplit, urlunsplit; r = urlsplit('https://example.com/a/b?x=1#frag'). You can access r.scheme, r.netloc, r.path, r.query, and r.fragment. To rebuild the original URL from the parsed result, use urlunsplit(r). This approach is common when you need to inspect or modify individual parts of a URL.

Differences from urlparse: urlsplit does not separate a semicolon-delimited parameters portion within the path (it provides only scheme, netloc, path, query, and fragment). This makes urlsplit slightly more efficient for typical URL handling. The signature is urlsplit(url, scheme='', allow_fragments=True); if allow_fragments is False, the fragment is not treated as a separate component and remains part of the path.

Notes: urlsplit can handle standard URL formats, including percent-encoding and IPv6 literals in the netloc. For parsing the query string into parameters, you would typically use parse_qsl or parse_qs on the query component. Relative URLs can also be parsed, yielding empty scheme and netloc.
