To be honest, this made sense to me.  I assumed the author wants you
to be able to do the following:

ask_number("Give me an even number between 1 and 10", 1, 10, 2)

The solution would be:

def ask_number(question, low, high, step=1):
	"""Ask for a number within the range"""
	response = None
	while response not in range(low, high, step):
		response =  int(raw_input(question))
	return response

But I definitely agree that he said it very, very badly.
