创建时间戳元组python

Question

我想创建一个时间戳元组。 如果我定义一个函数

def time_stamps(starttime,endtime,intervals):
    #start time of tuple like 08:00:00
    #End time of tuple like 21:00:00
    #With Intervals of 60 or 30 0r 90 minutes.
    #example  : if i call the function 
    #x = time_stamps(08:00:00,21:00:00,00:30:00)
    #It should generate a tuple like this
    #('08:00:00','08:30:00','09:00:00',....,'20:30:00','21:00:00)

我迷路了。请帮帮我。 谢谢

使用dateutils's parser将字符串格式的时间解析为datetime对象。然后我们可以很容易地基于时间增量计算计数，用它我们可以生成一个元组

from dateutil import parser
def time_stamps(starttime,endtime,intervals):
    start = parser.parse(starttime)
    end   = parser.parse(endtime)
    intervals = parser.parse(intervals) - parser.parse('00:00:00')
    count = int((end-start)/intervals)
    return tuple(( str((start+i*intervals).time()) for i in range(count+1)))

>>> time_stamps('10:00:00', '12:00:00', '00:30:00')
('10:00:00', '10:30:00', '11:00:00', '11:30:00', '12:00:00')
