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。

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)))

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)

下面是bash脚本获得工作日列表的一行代码，这是python 3。很容易修改为任何东西，末尾的int是你想要的过去的天数。

python -c "import sys,datetime; print('\n'.join([(datetime.datetime.today() - datetime.timedelta(days=x)).strftime(\"%Y/%m/%d\") for x in range(0,int(sys.argv[1])) if (datetime.datetime.today() - datetime.timedelta(days=x)).isoweekday()<6]))" 10

这里是提供开始(或者确切地说，结束)日期的变体

python -c "import sys,datetime; print('\n'.join([(datetime.datetime.strptime(sys.argv[1],\"%Y/%m/%d\") - datetime.timedelta(days=x)).strftime(\"%Y/%m/%d \") for x in range(0,int(sys.argv[2])) if (datetime.datetime.today() - datetime.timedelta(days=x)).isoweekday()<6]))" 2015/12/30 10

这里是任意开始和结束日期的变体。并不是说这不是非常有效，而是在bash脚本中放入for循环很好:

python -c "import sys,datetime; print('\n'.join([(datetime.datetime.strptime(sys.argv[1],\"%Y/%m/%d\") + datetime.timedelta(days=x)).strftime(\"%Y/%m/%d\") for x in range(0,int((datetime.datetime.strptime(sys.argv[2], \"%Y/%m/%d\") - datetime.datetime.strptime(sys.argv[1], \"%Y/%m/%d\")).days)) if (datetime.datetime.strptime(sys.argv[1], \"%Y/%m/%d\") + datetime.timedelta(days=x)).isoweekday()<6]))" 2015/12/15 2015/12/30

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)

(下同)

import datetime
from time import mktime

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

def date_range(how_many=7):
    for x in range(0, how_many):
        some_date = datetime.datetime.today() - datetime.timedelta(days=x)
        some_datetime = convert_date_to_datetime(some_date.date())
        yield some_datetime

def pick_two_dates(how_many=7):
    a = b = convert_date_to_datetime(datetime.datetime.now().date())
    for each_date in date_range(how_many):
        b = a
        a = each_date
        if a == b:
            continue
        yield b, a

另一个向前或向后计数的例子，从桑迪普的回答开始。

from datetime import date, datetime, timedelta
from typing import Sequence
def range_of_dates(start_of_range: date, end_of_range: date) -> Sequence[date]:

    if start_of_range <= end_of_range:
        return [
            start_of_range + timedelta(days=x)
            for x in range(0, (end_of_range - start_of_range).days + 1)
        ]
    return [
        start_of_range - timedelta(days=x)
        for x in range(0, (start_of_range - end_of_range).days + 1)
    ]

start_of_range = datetime.today().date()
end_of_range = start_of_range + timedelta(days=3)
date_range = range_of_dates(start_of_range, end_of_range)
print(date_range)

给了

[datetime.date(2019, 12, 20), datetime.date(2019, 12, 21), datetime.date(2019, 12, 22), datetime.date(2019, 12, 23)]

and

start_of_range = datetime.today().date()
end_of_range = start_of_range - timedelta(days=3)
date_range = range_of_dates(start_of_range, end_of_range)
print(date_range)

给了

[datetime.date(2019, 12, 20), datetime.date(2019, 12, 19), datetime.date(2019, 12, 18), datetime.date(2019, 12, 17)]

请注意，开始日期包含在返回中，因此如果需要四个总日期，请使用timedelta(days=3)
