我想创建一个日期列表，从今天开始，倒退任意天数，比如说，在我的示例中是100天.还有比这更好的办法吗？
import datetime
a = datetime.datetime.today()
numdays = 100
dateList = []
for x in range (0, numdays):
dateList.append(a - datetime.timedelta(days = x))
print dateList

稍微好一点.
base = datetime.datetime.today()
date_list = [base - datetime.timedelta(days=x) for x in range(numdays)]
