Python圆类实现：定义、属性、方法和计算

class Circle: def init(self, x, y, radius, r, g, b): self.x = x self.y = y self.radius = radius self.r = r self.g = g self.b = b

def set_x(self, x):
    self.x = x

def set_y(self, y):
    self.y = y

def set_radius(self, radius):
    self.radius = radius

def set_color(self, r, g, b):
    self.r = r
    self.g = g
    self.b = b

def get_x(self):
    return self.x

def get_y(self):
    return self.y

def get_radius(self):
    return self.radius

def get_color(self):
    return (self.r, self.g, self.b)

def get_circumference(self):
    return 2 * 3.14 * self.radius

def get_area(self):
    return 3.14 * self.radius ** 2
