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)

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

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))

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)

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)

从这个问题的标题中，我希望找到类似range()的东西，这将让我指定两个日期并创建一个包含所有日期的列表。这样，如果事先不知道，就不需要计算这两个日期之间的天数。

所以，冒着有点跑题的风险，这句话就可以了:

import datetime
start_date = datetime.date(2011, 1, 1)
end_date   = datetime.date(2014, 1, 1)

dates_2011_2013 = [ start_date + datetime.timedelta(n) for n in range(int ((end_date - start_date).days))]

所有功劳都归于这个答案!
