The if is alwasys returning True!

pyg = 'ay'

original = raw_input('Enter a word: ')
low_original = original.lower()

if len(low_original) > 0 and low_original.isalpha():
    print low_original
    if low_original[0] in ['a' , 'e' , 'i' , 'o' , 'u']:
            print "vowel"
            pyg_vowel = low_original + pyg
            print pyg_vowel
    else:
            print "consonant"
            pyg_cons = low_original[1: ] + low_original[0] + pyg
            print pyg_cons
else:
    print 'empty'
