The result objects from the urlsplit, urlparse and urldefrag functions are subclasses of the tuple type. These subclasses add the attributes listed in the documentation for those functions, the encoding and decoding support described in the previous section, as well as an additional method Return the re-combined version of the original URL as a string. This may differ from the original URL in that the scheme may be normalized to lower case and empty components may be dropped. Specifically, empty parameters, queries, and fragment identifiers will be removed unless the URL was parsed with missing_as_none=True. For urldefrag results, only empty fragment identifiers will be removed. For urlsplit and urlparse results, all noted changes will be made to the URL returned by this method. The result of this method remains unchanged if passed back through the original parsing function The following classes provide the implementations of the structured parse results when operating on str objects Concrete class for urldefrag results containing str data. The encode method returns a DefragResultBytes instance. Concrete class for urlparse results containing str data. The encode method returns a ParseResultBytes instance. Concrete class for urlsplit results containing str data. The encode method returns a SplitResultBytes instance. The following classes provide the implementations of the parse results when operating on bytes or bytearray objects Concrete class for urldefrag results containing bytes data. The decode method returns a DefragResult instance. Concrete class for urlparse results containing bytes data. The decode method returns a ParseResult instance. Concrete class for urlsplit results containing bytes data. The decode method returns a SplitResult instance. Attribution: Adapted from Python Documentation under PSF-2.0.
