如何導入dateutil.rrule模塊在Python

Question

繼rrule examples，我發現我能以這種方式導入rrule對象：

from dateutil.rrule import * 
my_rrule = rrule(DAILY, count=5) 
print(list(my_rrule)) 

打印出預期的輸出

[datetime.datetime(2016, 11, 23, 16, 55, 30), datetime.datetime(2016, 11, 24, 16, 55, 30), datetime.datetime(2016, 11, 25, 16, 55, 30), datetime.datetime(2016, 11, 26, 16, 55, 30), datetime.datetime(2016, 11, 27, 16, 55, 30)] 

但是，我喜歡保持對模塊的引用，所以我試圖導入並像這樣使用它：

import dateutil.rrule 
my_rrule = dateutil.rrule.rrule(DAILY, count=5) 

然而，這導致NameError：

Traceback (most recent call last): 
    File "/home/kurt/dev/scratch/Furion_scheduler/recurring_interval.py", line 18, in <module> 
    my_rrule = dateutil.rrule.rrule(DAILY, count=5) 
NameError: name 'DAILY' is not defined 

這是怎麼回事錯在這裏？

嘗試from dateutil.rrule import rrule, DAILY。
