For those of you who might be following Asheesh's Python classes and struggling (as am I) with the excercises:

   The code Allan Downey tells us to use in Chapter 15, Ex.4 seems not to work:

from World import *
world = World()

The wait_for_user function is defined in TurtleWorld, not in World.

Substituting TurtleWorld  for World in the two places that it appears, seems to solve the problem.
