What I would do is keep a variable delta that gets added to or
subtracted from the current guess, depending on whether the guess is too
high or too low. Each time through the loop, make delta smaller by
dividing by two unless delta is already down to 1.
Are you reading Python Programming for the absolute beginner? This
problem is exercise 4 for chapter 3 in my copy. Have you tried exercises
1-3? They are not so hard as this one.
