def best_match(self, matches, default=None):
overrides werkzeug.datastructures.Accept.best_match

Given a list of supported values, finds the best match from the list of accepted values.

Language tags are normalized for the purpose of matching, but are returned unchanged.

If no exact match is found, this will fall back to matching the first subtag (primary language only), first with the accepted values then with the match values. This partial is not applied to any other language subtags.

The default is returned if no exact or fallback match is found.

Parameters
matchesA list of supported languages to find a match.
defaultThe value that is returned if none match.
def _value_matches(self, value, item):
overrides werkzeug.datastructures.Accept._value_matches
Check if a value matches a given accept item.
