python 中稳健且完整的扩展或 RRULE
使用 dateutil.rrulestr，我设法扩展一些重复，例如看起来像这样的重复：
DTSTART;TZID=Europe/Zurich:20100930T183000
DTEND;TZID=Europe/Zurich:20100930T193000
RRULE:FREQ=DAILY;UNTIL=20101005T163000Z
BEGIN:VTIMEZONE
...
使用例如：
my_rrule.between(datetime.datetime(2010, 10, 2, 11, 00, tzinfo=pytz.utc),
datetime.datetime(2010, 10, 9, 11, 00, tzinfo=pytz.utc)))
但是，这只给我事件的开始日期时间，而不是结束日期时间。 有没有办法也获得结束时间？ （比我自己计算开始结束增量并将其应用于每个开始时间更干净）。
此外，某些重复可以针对全天事件，并采用以下形式：
DTSTART;VALUE=DATE:20120225
DTEND;VALUE=DATE:20120226
RRULE:FREQ=WEEKLY;BYDAY=SA
BEGIN:VTIMEZONE
...
如果我尝试使用相同的 Between() 调用来扩展此重复，我会收到错误：
TypeError: can't compare offset-naive and offset-aware datetimes
是否有一些查询适用于任何类型的重复（理想情况下返回日期或日期时间值，具体取决于情况）？
Using dateutil.rrulestr, I manage to expand some recurrences, for example one that looks like:
DTSTART;TZID=Europe/Zurich:20100930T183000
DTEND;TZID=Europe/Zurich:20100930T193000
RRULE:FREQ=DAILY;UNTIL=20101005T163000Z
BEGIN:VTIMEZONE
...
using for example:
my_rrule.between(datetime.datetime(2010, 10, 2, 11, 00, tzinfo=pytz.utc),
datetime.datetime(2010, 10, 9, 11, 00, tzinfo=pytz.utc)))
However, this gives me only the start datetimes for the events, not the end datetimes.
Is there a way to get the end times too ? (cleaner than computing the start-end delta myself and applying it to every start time).
Also, some recurrences can be for all-day events and be in the form:
DTSTART;VALUE=DATE:20120225
DTEND;VALUE=DATE:20120226
RRULE:FREQ=WEEKLY;BYDAY=SA
BEGIN:VTIMEZONE
...
If I try to expand this one with the same between() call, I get an error:
TypeError: can't compare offset-naive and offset-aware datetimes
Is there some query that would work for any kind of recurrence (ideally returning date or datetime values, depending on the case) ?

dateutil.rrule和朋友们没有持续时间的概念：他们正在重复时间瞬间的规则。我的解决方案是用自定义类替换 rruleset，该类也接受持续时间（或提供默认持续时间）。
然后，我可以生成事件，并附加每个事件的持续时间，以确定间隔。
dateutil.rruleand friends have no concept of durations: they are repeating rules of instants in time.My solution was to replace
rrulesetwith a custom class, that also accepts a duration (or provides a default one).Then, I can generate occurrences, and tack onto each occurrence it's duration, to determine the interval.
