python datetime模块

1、获取日期列表
/Users/nisj/PycharmProjects/EsDataProc/bi-static/date_list.py

 # -*- coding=utf-8 -*-
 import datetime

 def dateRange(beginDate, endDate):
     dates = []
     dt = datetime.datetime.strptime(beginDate, "%Y-%m-%d")
     date = beginDate[:]
     while date <= endDate:
         dates.append(date)
         dt = dt + datetime.timedelta(1)
         date = dt.strftime("%Y-%m-%d")
     return dates

 if __name__ == '__main__':
     for date in dateRange('2016-10-01', '2017-01-01'):
         print (date)
