<｜begin▁of▁sentence｜>### Instruction:
Given a Python script with defined ShapeDrawer classes for drawing different shapes like circles, squares, and triangles, can you register all these ShapeDrawer classes using the register_namespace function in the ShapeDrawerDirectory to allow a program to dynamically utilize these classes for drawing various shapes?
### Response:
# You would first define a namespace with some ShapeDrawer classes.
namespace = {
    'CircleDrawer': CircleDrawer,
    'SquareDrawer': SquareDrawer,
    'TriangleDrawer': TriangleDrawer
}

# Then you register all ShapeDrawer classes in the given namespace.
ShapeDrawerDirectory.ShapeDrawerDirectory.register_namespace(namespace)
