根据我自己的回答:

import datetime;
print [(datetime.date.today() - datetime.timedelta(days=x)).strftime('%Y-%m-%d') for x in range(-5, 0)]

输出:

['2017-12-11', '2017-12-10', '2017-12-09', '2017-12-08', '2017-12-07']

区别在于我得到的是'date'对象，而不是'datetime '对象。datetime”。

Matplotlib相关

from matplotlib.dates import drange
import datetime

base = datetime.date.today()
end  = base + datetime.timedelta(days=100)
delta = datetime.timedelta(days=1)
l = drange(base, end, delta)

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")

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

import datetime    
def date_generator():
    cur = base = datetime.date.today()
    end  = base + datetime.timedelta(days=100)
    delta = datetime.timedelta(days=1)
    while(end>base):
        base = base+delta
        print base

date_generator()

如果有两个日期，你需要范围试试

from dateutil import rrule, parser
date1 = '1995-01-01'
date2 = '1995-02-28'
datesx = list(rrule.rrule(rrule.DAILY, dtstart=parser.parse(date1), until=parser.parse(date2)))
