定义手机类，手机有品牌，价格和颜色三个属性，有打电call和sendMessage两个功能

下面是一个简单的Python示例代码，定义了一个手机类，它具有品牌、价格和颜色三个属性，以及打电话和发送短信两个方法：

class Phone:
    def __init__(self, brand, price, color):
        self.brand = brand
        self.price = price
        self.color = color
        
    def call(self, number):
        print("Calling {}...".format(number))
        
    def send_message(self, number, message):
        print("Sending message to {}: {}".format(number, message))

使用示例：

# 创建一个手机对象
my_phone = Phone("Apple", 999, "Black")

# 访问属性
print("My phone is a {} phone, which costs {} dollars and has a {} color.".format(my_phone.brand, my_phone.price, my_phone.color))

# 调用方法
my_phone.call("123456789")
my_phone.send_message("123456789", "Hello!")

输出：

My phone is a Apple phone, which costs 999 dollars and has a Black color.
Calling 123456789...
Sending message to 123456789: Hello!
