python中类的学习笔记(源码版)
#定义一个类(define a>class Cat: #属性(attribution)#方法(methods)
def eat(self):
print("cat is eating a fish.")
def drink(slef):
print("cat is drinking milk.")
def introduce(self):
print("%s's age is %d."%(self.chinese_name,self.age))
#创建一个对象(creating an object)
tom = Cat()
#调用一个对象的方法(method to invoke an object）
tom.eat()
tom.drink()
#蠢办法添加属性(stupid method to add attributions)
tom.chinese_name = "汤姆"
tom.age = 18
#获取对象的属性(the first way to getproperties of objects )
tom.introduce()
#创建多个对象，这里创建第二个对象blue_cat(create multiple objects,and the second creates bule cat)
blue_cat = Cat()
blue_cat.chinese_name = "蓝猫"
blue_cat.age = 8
blue_cat.introduce()
