Python的命名元组代替手动定义类

Python为什么伟大，就因为有命名元组（Namedtuple），好吧，也许有点夸大了。看示例吧

# Python为什么伟大: Namedtuples，命名元组
# 使用 命名元组 比定义一个类，代码要短的多。

>>> from collections import namedtuple
>>> Car = namedtuple('Car', 'color mileage')

# Our new "Car" class works as expected:
>>> my_car = Car('red', 3812.4)
>>> my_car.color
'red'
>>> my_car.mileage
3812.4

# We get a nice string repr for free:
>>> my_car
Car(color='red' , mileage=3812.4)

# Like tuples, namedtuples are immutable:
>>> my_car.color = 'blue'
