It can handle matching mime-types against a list of media-ranges. See section 14.1 of the HTTP specification [RFC 2616] for a complete explanation. http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html#sec14.1 Contents: - parse_mime_type(): Parses a mime-type into its component parts. - parse_media_range(): Media-ranges are mime-types with wild-cards and a 'q' quality parameter. - quality(): Determines the quality ('q') of a mime-type when compared against a list of media-ranges. - quality_parsed(): Just like quality() except the second parameter must be pre-parsed. - best_match(): Choose the mime-type with the highest quality ('q') from a list of candidates. i(tabsolute_import(treduceNs0.1.3s Joe Gregoriosjoe@bitworking.orgs MIT LicensetcC@s°|jdƒ}tg|dD]7}tg|jddƒD]}|jƒ^q9ƒ^qƒ}|djƒ}|dkr‚d}n|jdƒ\}}|jƒ|jƒ|fS(sUParses a mime-type into its component parts. Carves up a mime-type and returns a tuple of the (type, subtype, params) where 'params' is a dictionary of all the parameters for the media range.

Find the best match for a given mime-type against a list of media_ranges that have already been parsed by parse_media_range().

Takes a list of supported mime-types and finds the best match for all the media-ranges listed in header. The value of header must be a string that conforms to the format of the HTTP Accept: header. The value of 'supported' is a list of mime-types. The list of supported mime-types should be sorted in order of increasing desirability, in case of a situation where there is a tie. >>> best_match(['application/xbel+xml', 'text/xml'], 'text/*;q=0.5,*/*; q=0.1') 'text/xml' R,iii˙˙˙˙iR(t _filter_blankRRtappendR*tsort(t supportedtheadert split_headerR.t parsed_headertweighted_matchestposR ((sK/tmp/pip-build-kpPAdC/google-api-python-client/googleapiclient/mimeparse.pyt best_match‘s   cc@s)x"|D]}|jƒr|VqqWdS(N(R (tiR((sK/tmp/pip-build-kpPAdC/google-api-python-client/googleapiclient/mimeparse.pyR0Źs  (t__doc__t __future__Rt functoolsRRt __version__t __author__t __email__t __license__t __credits__RRR*R+R/R9R0(((sK/tmp/pip-build-kpPAdC/google-api-python-client/googleapiclient/mimeparse.pyts    "
