python高效编程技巧2（如何为元组的每个元素命名，提高程序的可读性）

#!/usr/bin/env python
# -*- coding:utf-8 -*-

# 1、定义类似其他语言的枚举类型
NAME = 0
AGE = 1
student = ("jim", "16", "male")
print student[NAME]

# 2、使用标准库中的collections.nametuple代替内置的tuple
from collections import namedtuple

student = namedtuple("student", ["name", "age", "sex"])
first_student = student("tom", "12", "femal")
print first_student.name
