Python:

In shape.py, create a Shape class with these methods.

__init__(), a class constructor what sets an objects x,y coordinates.

move(), a method to move objects to new x,y coordinates.

location(), a method that returns a tuple containing an object x,y coordinates.

In the Shape class complete the location() method.

The Shape class provides methods to set a shapes x,y coordinates, to move the shape to a new set of coordinates, and to report the shapes location as a tuple containing the objects x,y coordinates. You have to complete the location() method.

Heres some code to get you started on shape.py. Its based on the source code for the Shape class on p. 30 of The Quick Python Book.
