我知道这个回答有点晚，但我也遇到了同样的问题，我认为Python的内部范围函数在这方面有点缺乏，所以我在我的util模块中重写了它。

from __builtin__ import range as _range
from datetime import datetime, timedelta

def range(*args):
    if len(args) != 3:
        return _range(*args)
    start, stop, step = args
    if start < stop:
        cmp = lambda a, b: a < b
        inc = lambda a: a + step
    else:
        cmp = lambda a, b: a > b
        inc = lambda a: a - step
    output = [start]
    while cmp(start, stop):
        start = inc(start)
        output.append(start)

    return output

print range(datetime(2011, 5, 1), datetime(2011, 10, 1), timedelta(days=30))

我知道这个问题已经有人回答了，但为了历史的目的，我还是把我的答案写下来，因为我认为这是直截了当的。

import numpy as np
import datetime as dt
listOfDates=[date for date in np.arange(firstDate,lastDate,dt.timedelta(days=x))]

当然，它不会像代码高尔夫那样赢得任何东西，但我认为它很优雅。

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)

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, timezone


start_date = '2022_01_25'
end_date = '2022_01_30'

start = datetime.strptime(start_date, "%Y_%m_%d")
print(type(start))
end =  datetime.strptime(end_date, "%Y_%m_%d")
##pDate = str(pDate).replace('-', '_')
number_of_days = (end - start).days

print("number_of_days: ", number_of_days)

##
date_list = []
for day in range(number_of_days):
    a_date = (start + timedelta(days = day)).astimezone(timezone.utc)
    a_date = a_date.strftime('%Y-%m-%d')
    date_list.append(a_date)

print(date_list)
