处理日期

yesterday 表示昨天，例如：2020-03-09

yesterday = date.today() + timedelta(days = -1)
year = str(yesterday)[0:4]
def get_month(name):
if str(name)[5:6] == '0':return str(name)[6:7]
else: return str(name)[5:7]
def get_date(name):
if str(name)[9:10] == '0':return str(name)[10:11]
else: return str(name)[9:11]
