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 Nr# z&String contains unknown ISO components)�_parse_isodater& r( �_parse_isotimer r )r �dt_str� components�posr r r r ; s I zisoparser.isoparsec C s4 | � |�\}}|t|�k r,tdd�|� ��t|� 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 z String contains unknown ISO zcomponents: {})r+ r& r �formatr )r Zdatestrr. r/ r r r � parse_isodate� s �zisoparser.parse_isodatec C s 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 )r r, )r �timestrr r r � parse_isotime� s zisoparser.parse_isotimeTc C s | j ||d�S )a Parse a valid ISO time zone string.
