How to implement the object oriented pattern?
现在让我们来看看如何实施面向对象模式。
class Parrot:
# class attribute
species = "bird"
# instance attribute
def __init__(self, name, age):
self.name = name
self.age = age
# instantiate the Parrot class
blu = Parrot("Blu", 10)
woo = Parrot("Woo", 15)
# access the class attributes
print("Blu is a {}".format(blu.__class__.species))
print("Woo is also a {}".format(woo.__class__.species))
# access the instance attributes
print("{} is {} years old".format( blu.name, blu.age))
print("{} is {} years old".format( woo.name, woo.age))
