Python Rrule-reading'；频率''；间隔'；，etc价值观？

如何从Rrule中提取“频率”、“间隔”等值

from dateutil.rrule import *

my_rrule = rrule(freq=DAILY, interval=2, count=3)
print(str(my_rrule))
print(my_rrule.count())
print(my_rrule.interval())

>
DTSTART:20190130T025306
RRULE:FREQ=每日；间隔=2；计数=3
3.
回溯（最近一次呼叫最后一次）：
文件“/home/pi/test2.py”，第6行，在
打印（my_rrule.interval（））
AttributeError:“rrule”对象没有属性“interval”
>>>

此方法读取“计数”属性值，但因“间隔”、“频率”等而中断。

更改代码

print(my_rrule.interval())

到

您可以从rrule的init函数中得到一个线索，它将interval存储为类中的_interval，这意味着您最好不要尝试从外部使用此变量，因为实例可能会通过更改其值或其逻辑依赖于此而产生副作用

def __init__(self, freq, dtstart=None,
             interval=1, wkst=None, count=None, until=None, bysetpos=None,
             bymonth=None, bymonthday=None, byyearday=None, byeaster=None,
             byweekno=None, byweekday=None,
             byhour=None, byminute=None, bysecond=None,
             cache=False):
    super(rrule, self).__init__(cache)
    global easter
    if not dtstart:
        if until and until.tzinfo:
            dtstart = datetime.datetime.now(tz=until.tzinfo).replace(microsecond=0)
        else:           
            dtstart = datetime.datetime.now().replace(microsecond=0)
    elif not isinstance(dtstart, datetime.datetime):
        dtstart = datetime.datetime.fromordinal(dtstart.toordinal())
    else:
        dtstart = dtstart.replace(microsecond=0)
    self._dtstart = dtstart
    self._tzinfo = dtstart.tzinfo
    self._freq = freq
    self._interval = interval
    self._count = count

下面是我的操作方法（格式为（））：

很好！感谢您的解释（请注意……“\u freq”将返回相应的整数，即DAILY=3）。此版本已在此处发布：

print(my_rrule._interval)
