编写程序，创建基类Animal，其成员包括实例属性color,实例方法getColor()和setColor()分别用来获取和设置color的值，实例方法 abilities()输出字符串“Animals can run”。创建派生类Dog，继承Animal类，新增实例属性name，新增实例方法getName()和setName()分别用来获取和设置name的值，重写基类的实例方法 abilities()，输出字符串“Dogs can run and bark”。利用__init__()构造方法完成Animal和Dog类的对象初始化工作，并编写测试代码python编写完整代码和步骤

步骤如下：

1. 定义基类Animal，包括实例属性color，实例方法getColor()和setColor()，实例方法abilities()。

class Animal:
    def __init__(self, color):
        self.color = color

    def getColor(self):
        return self.color

    def setColor(self, color):
        self.color = color

    def abilities(self):
        print("Animals can run")

2. 定义派生类Dog，继承Animal类，新增实例属性name，新增实例方法getName()和setName()，重写基类的实例方法abilities()。

class Dog(Animal):
    def __init__(self, name, color):
        super().__init__(color)
        self.name = name

    def getName(self):
        return self.name

    def setName(self, name):
        self.name = name

    def abilities(self):
        print("Dogs can run and bark")

3. 编写测试代码，分别创建Animal和Dog类的对象，并调用各自的方法进行测试。

# 创建Animal对象并测试
animal = Animal("brown")
print("Animal color:", animal.getColor())
animal.setColor("white")
print("Animal color after setting:", animal.getColor())
animal.abilities()

# 创建Dog对象并测试
dog = Dog("Buddy", "black")
print("Dog name:", dog.getName())
print("Dog color:", dog.getColor())
dog.setName("Charlie")
print("Dog name after setting:", dog.getName())
dog.abilities()

完整代码如下：

class Animal:
    def __init__(self, color):
        self.color = color

    def getColor(self):
        return self.color

    def setColor(self, color):
        self.color = color

    def abilities(self):
        print("Animals can run")


class Dog(Animal):
    def __init__(self, name, color):
        super().__init__(color)
        self.name = name

    def getName(self):
        return self.name

    def setName(self, name):
        self.name = name

    def abilities(self):
        print("Dogs can run and bark")


# 测试代码
# 创建Animal对象并测试
animal = Animal("brown")
print("Animal color:", animal.getColor())
animal.setColor("white")
print("Animal color after setting:", animal.getColor())
animal.abilities()

# 创建Dog对象并测试
dog = Dog("Buddy", "black")
print("Dog name:", dog.getName())
print("Dog color:", dog.getColor())
dog.setName("Charlie")
print("Dog name after setting:", dog.getName())
dog.abilities()
