If locales are not given, languages and region are used to construct locales for translation. :type languages: list :param locales: A list of locale codes, e.g. ['fr-PF', 'qu-EC', 'af-NA']. The parser uses only these locales to translate date string. :type locales: list :param region: A region code, e.g. 'IN', '001', 'NE'. If locales are not given, languages and region are used to construct locales for translation. :type region: str :param try_previous_locales: If True, locales previously used to translate date are tried first. :type try_previous_locales: bool :param use_given_order: If True, locales are tried for translation of date string in the order in which they are given. :type use_given_order: bool :param settings: Configure customized behavior using settings defined in :mod:`dateparser.conf.Settings`. :type settings: dict :param detect_languages_function: A function for language detection that takes as input a `text` and a `confidence_threshold`, and returns a list of detected language codes. Note: this function is only used if ``languages`` and ``locales`` are not provided. :type detect_languages_function: function :return: A parser instance :raises: ``ValueError``: Unknown Language, ``TypeError``: Languages argument must be a list, ``SettingValidationError``: A provided setting is not valid.

In the example below, since no day information is present, the day is assumed to be current day ``16`` from *current date* (which is June 16, 2015, at the moment of writing this). Hence, the level of precision is ``month``: >>> DateDataParser().get_date_data('March 2015') DateData(date_obj=datetime.datetime(2015, 3, 16, 0, 0), period='month', locale='en') Similarly, for date strings with no day and month information present, level of precision is ``year`` and day ``16`` and month ``6`` are from *current_date*. >>> DateDataParser().get_date_data('2014') DateData(date_obj=datetime.datetime(2014, 6, 16, 0, 0), period='year', locale='en') Dates with time zone indications or UTC offsets are returned in UTC time unless specified using `Settings `__. >>> DateDataParser().get_date_data('23 March 2000, 1:21 PM CET') DateData(date_obj=datetime.datetime(2000, 3, 23, 13, 21, tzinfo=), period='day', locale='en') zInput type must be strrdrr{Nr&r) r<rrzrtrwrP_get_applicable_localesrur shortnamerrrp)rrrqresr{ parsed_dater r r!rs" +   zDateDataParser.get_date_datacOs6|j|i|}|j}td|}|di|jS)Nrpr )rrkeysr namedtuple)rargsr2rfields date_tupler r r!get_date_tuples  zDateDataParser.get_date_tuplec#sgfdd}|jr$|jD]}|D] }|||r"|Vqq|jr;|js;|js;|j|jjd}t ||_| j |j|j|j |j dD]}|D] }|||rZ|VqOqJ|jjru| j |jjd|j |j dD]}|VqodSdS)Nc3sRVstdd\}}|krd}|gdd<\}|dur'|VdSdS)zA generator instead of a static list to avoid calling pop_tz_offset_from_string if the first locale matches on unmodified date_string.
