    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 IntEnum
    NAME,AGE,SEX,EMAIL=range(4)
    s=('jim','16','male','jim8721@gmail.com')
    # 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','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')
