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`` or ``YYYYMM`` - ``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.sss`` or ``hh:mm:ss.ssssss`` (3-6 sub-second digits) Midnight is a special case for `hh`, as the standard supports both 00:00 and 24:00 as a representation. .. 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 is&String contains unknown ISO componentsN(t_parse_isodateRR Rt_parse_isotimeRR(Rtdt_strt componentstpos((sD/tmp/pip-install-xdEqop/python-dateutil/dateutil/parser/isoparser.pyR;s I)cCsM|j|ƒ\}}|t|ƒkrCtddj|ƒƒ‚nt|ŒS(sÞ 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 sString contains unknown ISO scomponents: {}(R#RRtformatR(RtdatestrR&R'((sD/tmp/pip-install-xdEqop/python-dateutil/dateutil/parser/isoparser.pyt parse_isodateŽs cCst|j|ƒŒS(sÜ 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$(Rttimestr((sD/tmp/pip-install-xdEqop/python-dateutil/dateutil/parser/isoparser.pyt parse_isotimeŸs cCs|j|d|ƒS(s Parse a valid ISO time zone string.
