An ISO-8601 datetime string consists of a date portion, followed optionally by a time portion - the date and time portions are separated by a single character separator, which is ``T`` in the official standard. Incomplete date formats (such as ``YYYY-MM``) may *not* be combined with a time portion. Supported date formats are: Common: - ``YYYY`` - ``YYYY-MM`` - ``YYYY-MM-DD`` or ``YYYYMMDD`` Uncommon: - ``YYYY-Www`` or ``YYYYWww`` - ISO week (day defaults to 0) - ``YYYY-Www-D`` or ``YYYYWwwD`` - ISO week and day The ISO week and day numbering follows the same logic as :func:`datetime.date.isocalendar`. Supported time formats are: - ``hh`` - ``hh:mm`` or ``hhmm`` - ``hh:mm:ss`` or ``hhmmss`` - ``hh:mm:ss.ssssss`` (Up to 6 sub-second digits) Midnight is a special case for `hh`, as the standard supports both 00:00 and 24:00 as a representation. The decimal separator can be either a dot or a comma. .. caution:: Support for fractional components other than seconds is part of the ISO-8601 standard, but is not currently implemented in this parser. Supported time zone offset formats are: - `Z` (UTC) - `±HH:MM` - `±HHMM` - `±HH` Offsets will be represented as :class:`dateutil.tz.tzoffset` objects, with the exception of UTC, which will be represented as :class:`dateutil.tz.tzutc`. Time zone offsets equivalent to UTC (such as `+00:00`) will also be represented as :class:`dateutil.tz.tzutc`. :param dt_str: A string or stream containing only an ISO-8601 datetime string :return: Returns a :class:`datetime.datetime` representing the string. Unspecified components default to their lowest value. .. warning:: As of version 2.7.0, the strictness of the parser should not be considered a stable part of the contract. Any valid ISO-8601 string that parses correctly with the default settings will continue to parse correctly in future versions, but invalid strings that currently fail (e.g. ``2017-01-01T00:00+00:00:00``) are not guaranteed to continue failing in future versions if they encode a valid date. .. versionadded:: 2.7.0 Nr%z&String contains unknown ISO componentsrdays)_parse_isodater(r*_parse_isotimerrr)rdt_str componentsposr r rr ;sK  zisoparser.isoparsecCs:||\}}|t|kr2tdd|dt|S)z Parse the date portion of an ISO string. :param datestr: The string portion of an ISO string, without a separator :return: Returns a :class:`datetime.date` object zString contains unknown ISO zcomponents: {!r}r)r1r(rformatdecoder)rZdatestrr4r5r r r parse_isodates  zisoparser.parse_isodatecCs&||}|ddkrd|d<t|S)z Parse the time portion of an ISO string. :param timestr: The time portion of an ISO string, without a separator :return: Returns a :class:`datetime.time` object rr.)r2r)rtimestrr4r r r parse_isotimes  zisoparser.parse_isotimeTcCs|j||dS)a Parse a valid ISO time zone string.
