、设计一个Circle(圆）类，包括半径、颜色等属性，且包括计算其周长和面积的方法。创建Circle类的实例对象，传入其半径和颜色，计算出该实例对象的周长和面积

以下是一个基本的实现：

import math

class Circle:
    def __init__(self, radius, color):
        self.radius = radius
        self.color = color
    
    def circumference(self):
        return 2 * math.pi * self.radius
    
    def area(self):
        return math.pi * self.radius ** 2

# 创建Circle类的实例对象
my_circle = Circle(5, "red")

# 计算出该实例对象的周长和面积
circumference = my_circle.circumference()
area = my_circle.area()

print(f"The circumference of my circle is {circumference:.2f}")
print(f"The area of my circle is {area:.2f}")

运行结果：

The circumference of my circle is 31.42
The area of my circle is 78.54
