This could be an interesting error

ex='Hey buddy get away from the car'
newex = ex.split()

print (newex)
wait = input ("          Wait")

def pigword(test):
    for x in range(len(test)):
        if test[x] in "AEIOUaeiou":
            stem = test [x:]
            prefix = test [:x]
            pigword = stem + prefix + "ay"
            print ("Stem ",stem)
            print ("Prefix",prefix)
            print (pigword)
            break
    return (pigword)

for x in range(len(newex)):
    sentence = sentence + pigword(newex[x])+ " "
    print (sentence)
    wait = input ("          Wait")

The program seems to work and it does work with everything I have
tried so far.  The one exception is if you change "the" to "my" (in
the first line) the program crashes.
