I was bothered about apple and orange not having the correct indefinite article. To fix this, I nestled another for/else in the primary for/else:

fruits = ['banana', 'apple', 'orange', 'tomato', 'pear', 'grape']
vowels = ['a', 'e', 'i', 'o', 'u']
 
print 'You have...'
for f in fruits:
  if f == 'tomato':
    print 'A tomato is not a fruit!' # (It actually is.)
    break
  for v in vowels:
     if f[0] == v:
      print 'An', f
      break
  else:
    print 'A', f
else:
  print 'A fine selection of fruits!'

Is there a better way to write my addition to the code?

a ternary operator should do the the trick:

print 'An %s' % f if f[0] in vowels else "A %s" % f

its less code. But its also less readable. So you could argue if this is better or not. But you could use pythons in operator to make your code easier to read.
