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','[email protected]')
('eric','17','male','[email protected]')
('xander','16','female','[email protected]')方案一：
from enum import IntEnum
NAME,AGE,SEX,EMAIL=range(4)
s=('jim','16','male','[email protected]')
# print(NAME) # 0
class StudentEnum(IntEnum):
NAME=0
AGE=1
SEX=2
EMAIL=3
print(s[StudentEnum.NAME]) # jim
print(isinstance(StudentEnum.NAME,int)) # True方案二：
from collections import namedtuple
Student=namedtuple('Student',['name','age','sex','email'])
s2=Student('jim','16','male','[email protected]')
s3=Student('eric','16','male','[email protected]')
print(s2) # Student(name='jim', age='16', sex='male', email='[email protected]')
print(s3) # Student(name='eric', age='16', sex='male', email='[email protected]')
