您使用的datetime.datetime.date()方法：

datetime.datetime.now().date()

显然，以上表达式可以（并且应该恕我直言：）写成：

datetime.date.today()

You use the datetime.datetime.date() method:

datetime.datetime.now().date()

Obviously, the expression above can (and should IMHO :) be written as:

datetime.date.today()

您可以使用日期时间对象的date（）方法将datetime对象转换为日期，如下所示：

<datetime_object>.date()

You can convert a datetime object to a date with the date() method of the date time object, as follows:

<datetime_object>.date()

import time
import datetime

# use mktime to step by one day
# end - the last day, numdays - count of days to step back
def gen_dates_list(end, numdays):
  start = end - datetime.timedelta(days=numdays+1)
  end   = int(time.mktime(end.timetuple()))
  start = int(time.mktime(start.timetuple()))
  # 86400 s = 1 day
  return xrange(start, end, 86400)

# if you need reverse the list of dates
for dt in reversed(gen_dates_list(datetime.datetime.today(), 100)):
    print datetime.datetime.fromtimestamp(dt).date()

您可以输入以下代码形式（（今天的日期和日期和时间的名称）： datetime.datetime.now().strftime('%y-%m-%d %a %H:%M:%S')

’19 -09-09 Mon 17:37:56′

并输入以下代码（仅用于今天）：“ datetime.date.today().strftime('%y-%m-%d') 19-09-10”

对于对象： datetime.datetime.now().date() datetime.datetime.today().date() datetime.datetime.utcnow().date() datetime.datetime.today().time() datetime.datetime.utcnow().date() datetime.datetime.utcnow().time()

you could enter this code form for (today date & Names of the Day & hour) : datetime.datetime.now().strftime('%y-%m-%d %a %H:%M:%S')

’19-09-09 Mon 17:37:56′

and enter this code for (today date simply): datetime.date.today().strftime('%y-%m-%d') ’19-09-10′

for object : datetime.datetime.now().date() datetime.datetime.today().date() datetime.datetime.utcnow().date() datetime.datetime.today().time() datetime.datetime.utcnow().date() datetime.datetime.utcnow().time()
