Answer 1

import datetime
class student:
def __init__(self,Sno,Sname,Sbarthday,Sfaction):
self.Sage = 0
self.Sgarde = '优秀'
self.Sname = Sname
self.Sno = Sno
self.Sbarthday = datetime.datetime.strptime(Sbarthday,"%Y-%m-%d")
self.Sfaction = Sfaction
self.Setage(Sbarthday)
self.SetGarde(Sfaction)
def Setage(self,Sbarthday):
if (datetime.date.today().month - self.Sbarthday.month)>=0:
if (datetime.date.today().day - self.Sbarthday.day)<0 & (datetime.date.today().month - self.Sbarthday.month)==0:
self.Sage = datetime.date.today().year - self.Sbarthday.year -1
else:
self.Sage = datetime.date.today().year - self.Sbarthday.year
else:
self.Sage = datetime.date.today().year - self.Sbarthday.year -1

def SetGarde(self,Sfaction):
if self.Sfaction >= 80:
self.Sgarde = '优秀'
elif self.Sfaction >= 70 & self.Sfaction <80:
self.Sgarde = '良好'
elif self.Sfaction >= 60 & self.Sfaction <70:
self.Sgarde = '及格'
else:
self.Sgarde = '不及格'

text1 = student('2018061','张三','1999-10-27',68)
print("学号：{0} 姓名：{1} 年龄：{2} 分数：{3} 等级：{4}".format(text1.Sno,text1.Sname,text1.Sage,text1.Sfaction,text1.Sgarde))
