Python设计两个类： 一个点类，属性包括x，y坐标。 一个Rectangle类（矩形） ,属性有左上角和右下角的坐标，可以计算矩形的面积；可以判断点是否

在Python中，你可以设计如下的两个类：

class Point:
    def __init__(self, x, y):
        self.x = x
        self.y = y
    # 点的相关方法，比如获取坐标、打印等
    def get_coordinates(self):
        return (self.x, self.y)
    def __str__(self):
        return f"Point ({self.x}, {self.y})"

class Rectangle:
    def __init__(self, left_top_point, right_bottom_point):
        self.left_top = left_top_point
        self.right_bottom = right_bottom_point
        self.width = right_bottom_point.x - left_top_point.x
        self.height = right_bottom_point.y - left_top_point.y

    # 计算矩形面积
    def area(self):
        return self.width * self.height

    # 判断点是否在矩形内
    def contains_point(self, point):
        if point.get_coordinates()[0] >= self.left_top.x and \
                point.get_coordinates()[0] <= self.right_bottom.x and \
                point.get_coordinates()[1] >= self.left_top.y and \
                point.get_coordinates()[1] <= self.right_bottom.y:
            return True
        else:
            return False

    # 以字符串形式表示矩形
    def __str__(self):
        return f"Rectangle ({self.left_top}, {self.right_bottom}) with area {self.area()}"

# 示例
pt = Point(2, 3)
rect = Rectangle(Point(0, 0), Point(5, 7))
print(f"Point at ({pt.x}, {pt.y}): {pt}")
print(f"Rectangle ({rect.left_top}, {rect.right_bottom}): Area = {rect.area()}")
if rect.contains_point(pt):
    print("Point is inside the rectangle.")
else:
    print("Point is not inside the rectangle.")
