Make super- and subclass for a point. A point (x, y) in the plane can be represented by a class:

We can extend the Point class to also contain the representation of the point in polar coordinates. To this end, create a subclass PolarPoint whose constructor takes the polar representation of a point, (r, θ), as arguments. Store r and θ as attributes and call the superclass constructor with the corresponding x and y values (recall the relations x = r cos θ and y = r sin θ between Cartesian and polar coordinates). Add a __str__ method in class PolarPoint which prints out r, θ, x, and y. Verify the implementation by initializing three points and printing these points. Name of program file: PolarPoint.py.
