python3获取两个日期之间所有日期,以及比较大小的实例

import datetime 
#获取两个日期间的所有日期 
def getEveryDay(begin_date,end_date): 
 date_list = [] 
 begin_date = datetime.datetime.strptime(begin_date, "%Y-%m-%d") 
 end_date = datetime.datetime.strptime(end_date,"%Y-%m-%d") 
 while begin_date <= end_date: 
  date_str = begin_date.strftime("%Y-%m-%d") 
  date_list.append(date_str) 
  begin_date += datetime.timedelta(days=1) 
 return date_list 
print(getEveryDay('2016-01-01','2017-05-11')) 

import datetime
#比较大小
strftime = datetime.datetime.strptime("2017-11-02", "%Y-%m-%d")
strftime2 = datetime.datetime.strptime("2017-01-04", "%Y-%m-%d")
print("2017-11-02大于2017-01-04：",strftime>strftime2)
