python3获取两个日期之间所有日期，以及比较大小

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)
