我想用一个简单(不完整)的日期范围实现来发表我的意见:

from datetime import date, timedelta, datetime

class DateRange:
    def __init__(self, start, end, step=timedelta(1)):
        self.start = start
        self.end = end
        self.step = step

    def __iter__(self):
        start = self.start
        step = self.step
        end = self.end

        n = int((end - start) / step)
        d = start

        for _ in range(n):
            yield d
            d += step

    def __contains__(self, value):
        return (
            (self.start <= value < self.end) and 
            ((value - self.start) % self.step == timedelta(0))
        )

获取指定的开始日期和结束日期之间的日期范围(优化的时间和空间复杂性):

import datetime

start = datetime.datetime.strptime("21-06-2014", "%d-%m-%Y")
end = datetime.datetime.strptime("07-07-2014", "%d-%m-%Y")
date_generated = [start + datetime.timedelta(days=x) for x in range(0, (end-start).days)]

for date in date_generated:
    print date.strftime("%d-%m-%Y")

        )

是的，重新发明轮子.... 只要搜索论坛，你就会得到这样的东西:

from dateutil import rrule
from datetime import datetime

list(rrule.rrule(rrule.DAILY,count=100,dtstart=datetime.now()))

from datetime import datetime, timedelta
from dateutil import parser
def getDateRange(begin, end):
    """  """
    beginDate = parser.parse(begin)
    endDate =  parser.parse(end)
    delta = endDate-beginDate
    numdays = delta.days + 1
    dayList = [datetime.strftime(beginDate + timedelta(days=x), '%Y%m%d') for x in range(0, numdays)]
    return dayList

以下是我从自己的代码中创建的要点，这可能会有所帮助。(我知道这个问题太老了，但其他人可以用)

def convert_date_to_datetime(date_object):
    date_tuple = date_object.timetuple()
    date_timestamp = mktime(date_tuple)
    return datetime.datetime.fromtimestamp(date_timestamp)

        yield some_datetime
