假设学生系统中数据为固定格式：(名字，年龄，性别，邮箱)

('jack','16','male','jack3001@gmail.com')('eric','17','male','eric@qq.com')('xander','16','female','lucy123@yahoo.com')

方案一：

from enum import IntEnumNAME,AGE,SEX,EMAIL=range(4)s=('jim','16','male','jim8721@gmail.com')# print(NAME) # 0class StudentEnum(IntEnum): NAME=0 AGE=1 SEX=2 EMAIL=3print(s[StudentEnum.NAME]) # jimprint(isinstance(StudentEnum.NAME,int)) # True

方案二：

from collections import namedtupleStudent=namedtuple('Student',['name','age','sex','email'])s2=Student('jim','16','male','jim8721@gmail.com')s3=Student('eric','16','male','eric3421@gmail.com')print(s2) # Student(name='jim', age='16', sex='male', email='jim8721@gmail.com')print(s3) # Student(name='eric', age='16', sex='male', email='eric3421@gmail.com')
