     while True:
         try:
             s = raw_input(question).lower()[0]
             if s == 'y':
                 return True
             elif s == 'n':
                 return False
         except:
             pass     ## This traps the condition where a user just
presses enter
         print '\nplease select y, n, yes, or no\n'

Thanks for your suggestions, I put together the following based on them:
##############################################
def is_yes(question):
     while True:
         s = raw_input(question).lower()
         if s == 'y' or s == 'yes':
             return True
         elif s == 'n' or s == 'no':
             return False
         else:
             print '\nplease select y, n, yes, or no\n'
################################################

It seems to work perfectly :)
