python 日期格式

import datetime

#获取两个日期间的所有日期
def getEveryDay(begin_date,end_date):
    date_list = []
    #由日期格式转化为字符串格式的函数为：datetime.datetime.strftime()
    #由字符串格式转化为日期格式的函数为：datetime.datetime.strptime()
    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)
       #timedelta函数表示两个datetime的时间差
        begin_date += datetime.timedelta(days=1)
    return date_list
print(getEveryDay('2016-01-01','2017-05-11'))

import datetime
#将字符串格式转化为日期格式在进行比较大小
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)
