如何在列表中分别移动多个相同的矩形？

# 定义矩形类
class Rectangle:
    def __init__(self, x, y, width, height):
        self.x = x
        self.y = y
        self.width = width
        self.height = height

# 创建矩形列表
rectangles = []
rectangles.append(Rectangle(0, 0, 10, 10))
rectangles.append(Rectangle(20, 20, 15, 15))
rectangles.append(Rectangle(50, 50, 8, 8))

# 定义移动距离和方向
move_distance = 5
move_direction = "right"

# 遍历矩形列表，移动每个矩形
for rectangle in rectangles:
    if move_direction == "right":
        rectangle.x += move_distance
    elif move_direction == "left":
        rectangle.x -= move_distance
    elif move_direction == "up":
        rectangle.y -= move_distance
    elif move_direction == "down":
        rectangle.y += move_distance

# 打印移动后的矩形位置信息
for rectangle in rectangles:
    print("矩形位置：({}, {})，宽度：{}，高度：{}".format(rectangle.x, rectangle.y, rectangle.width, rectangle.height))
