Python_Class

1.创建类的关键字：class

2.构造函数__init__(),自动初始化属性值

class Cup:

    #构造函数，初始化属性值
    def __init__(self,capacity,color):
        self.capacity=capacity
        self.color=color

    def retain_water(self):
        print("杯子颜色："+self.color+"，杯子容量："+self.capacity+",正在装水.")

    def keep_warm(self):
        print("杯子颜色："+self.color+"，杯子容量："+self.capacity+",正在保温.")

cup1=Cup('450ml','红色')
cup2=Cup('700ml','黄色')
cup1.retain_water()
cup2.keep_warm()
