Here is a quick one
def main(): words = str(input("Input Sentence:")).split() for word in words: print(word[1:] + word[0] + "ay", end = " ") print () main()
A better solution would probably use list comprehension so you could actually use the output, but this does what you asked.
EDIT: This works for python3.x If you want it to work for python2 you are going to have a bit more fun. Just add the strings together for each word, then print the result string.
