你也可以使用日期序数来简化:

def date_range(start_date, end_date):
    for ordinal in range(start_date.toordinal(), end_date.toordinal()):
        yield datetime.date.fromordinal(ordinal)

或者像评论中建议的那样，你可以创建一个这样的列表:

date_range = [
    datetime.date.fromordinal(ordinal) 
    for ordinal in range(
        start_date.toordinal(),
        end_date.toordinal(),
    )
]

从上面的答案，我创建了这个例子的日期生成器

import datetime
date = datetime.datetime.now()
time = date.time()
def date_generator(date, delta):
  counter =0
  date = date - datetime.timedelta(days=delta)
  while counter <= delta:
    yield date
    date = date + datetime.timedelta(days=1)
    counter +=1

for date in date_generator(date, 30):
   if date.date() != datetime.datetime.now().date():
     start_date = datetime.datetime.combine(date, datetime.time())
     end_date = datetime.datetime.combine(date, datetime.time.max)
   else:
     start_date = datetime.datetime.combine(date, datetime.time())
     end_date = datetime.datetime.combine(date, time)
   print('start_date---->',start_date,'end_date---->',end_date)

你也可以使用日期序数来简化:

def date_range(start_date, end_date):
    for ordinal in range(start_date.toordinal(), end_date.toordinal()):
        yield datetime.date.fromordinal(ordinal)

    for ordinal in range(

        end_date.toordinal(),
    )
]

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()

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")
