aniso8601
=========
Another ISO 8601 parser for Python
----------------------------------
Features
========
* Pure Python implementation
* Python 3 support
* Logical behavior
- Parse a time, get a `datetime.time
`_
- Parse a date, get a `datetime.date
`_
- Parse a datetime, get a `datetime.datetime
`_
- Parse a duration, get a `datetime.timedelta
`_
- Parse an interval, get a tuple of dates or datetimes
- Parse a repeating interval, get a date or datetime [generator]
* UTC offset represented as fixed-offset tzinfo
* Parser separate from representation, allowing parsing to different
datetime formats
* No regular expressions
Installation
============
The recommended installation method is to use pip::
$ pip install aniso8601
Alternatively, you can download the source (git repository hosted at
[Bitbucket]) and install directly::
$ python setup.py install

Parsing datetimes
-----------------
To parse a typical ISO 8601 datetime string::
>>> import aniso8601
>>> aniso8601.parse_datetime('1977-06-10T12:00:00Z')
datetime.datetime(1977, 6, 10, 12, 0, tzinfo=+0:00:00 UTC)
Alternative delimiters can be specified, for example, a space::
>>> aniso8601.parse_datetime('1977-06-10 12:00:00Z', delimiter=' ')
datetime.datetime(1977, 6, 10, 12, 0, tzinfo=+0:00:00 UTC)
UTC offsets are supported::
>>> aniso8601.parse_datetime('1979-06-05T08:00:00-08:00')
datetime.datetime(1979, 6, 5, 8, 0, tzinfo=-8:00:00 UTC)
If a UTC offset is not specified, the returned datetime will be naive::
>>> aniso8601.parse_datetime('1983-01-22T08:00:00')
datetime.datetime(1983, 1, 22, 8, 0)
Leap seconds are currently not supported and attempting to parse one raises
a :code:`LeapSecondError`::
>>> aniso8601.parse_datetime('2018-03-06T23:59:60')
Traceback (most recent call last):
File "", line 1, in
File "aniso8601/time.py", line 131, in parse_datetime
return builder.build_datetime(datepart, timepart)
File "aniso8601/builder.py", line 300, in build_datetime

File "aniso8601/builder.py", line 253, in build_time
raise LeapSecondError('Leap seconds are not supported.')
aniso8601.exceptions.LeapSecondError: Leap seconds are not supported.
Parsing dates
-------------
To parse a date represented in an ISO 8601 string::
>>> import aniso8601
>>> aniso8601.parse_date('1984-04-23')
datetime.date(1984, 4, 23)
Basic format is supported as well::
>>> aniso8601.parse_date('19840423')
datetime.date(1984, 4, 23)
To parse a date using the ISO 8601 week date format::
>>> aniso8601.parse_date('1986-W38-1')
