Cheap and cheerful parser for iso8601 with zero flexibility.

parse_iso8601_badly.py

import datetime
import time

now = datetime.datetime.now()
now_iso = now.isoformat()

def parse_iso8601_badly(iso_str):
    date_str, time_str = iso_str.split('T')
    d = dict()
    d.update(zip(['hour', 'minute', 'second'],
                 map(int, map(round,  (map(float, time_str.split(':')))))))
    d.update(zip(['year', 'month', 'day'], map(int, date_str.split('-'))))
    return datetime.datetime(**d)


if __name__ == '__main__':
    d = parse_iso8601_badly(now_iso)
    print type(d), d

Problem with seconds when the value is >59.5 because it rounds to 60 which is invalid.
