two classes so that the client code provided in

RectangleClient.py file works as expected. See

Appendix for more information on the coordinate system these points and rectangles are

expected to be placed. Specifically,

Create a Point class with the following requirements:

Attributes:

@dotsx : $x-$coordinate of the point

@dotsy : y$-$coordinate of the point

Two readonly Properties:

$x$ : $x-$coordinate of the point

@$y$ : $y-$coordinate of the point

A constructor:

This takes two required arguments: $x$ and $y$ coordinates

One Method:

translate$($dx$,$dy$)$: method moves the point by $dx$ in $x-$direction and by $dy$ in $y-$

direction $($it updates the $\_x$ and $\_y$ attributes by adding $dx$ and dy to them

respectively$)$

Create a Rectangle class with the following requirements:

Three static attributes:

$$ DEFAULT$\_$WIDTH $($initialized to $1)$

$$ DEFAULT$\_$HEIGHT $($initialized to $1)$

rectangleCount $($initialized to $0,$ represents the count of rectangles

instantiated so far$)$

Attributes:

$\_$topLeft: an instance of Point class that denotes the top$-$left corner of the

rectangle.

$\_$ width: width of the rectangle $($cannot be negative or $0)$

@$,\_$height: height of the rectangle $($cannot be negative or $0)$

Three properties:

O topLeft: Getter should return the $\_$ topLeft attribute and the setter should

update the $\_$topLeft attribute.

width: The getter method should return the

width attribute. Knowing that

width cannot be negative or $0,$ the setter should check if client tries to set anfrom rectangle import Rectangle, Point
