For data with fixed format, they can be stored as tuples. Compared to dictionary, tuples save more space.
However if we want to access a certain data in a tuple, we need to use index, reducing the readability.
s = ("Jim", 20, "male", "firstname.lastname@example.org")
There are two solutions to increase readability: enumeration and namedtuple
NAME, AGE, SEX, EMAIL = range(4)
from enum import IntEnum class StudentEnum(IntEnum): NAME, AGE, SEX, EMAIL = range(4) [StudentEnum.NAME]
from collections import namedtuple Student = namedtuple('Student', ['name', 'age', 'sex', 'email']) std1 = Student('IZ', 18, 'male', 'email@example.com') std1.name std1.email
