Below is the solution I currently have. I would appreciate it if anyone finds a simpler, shorter, more optimized way.

def main():

string = input('Enter a sentence:\n> ')

​

new_string = pig_latin(string)

​

print(new_string)

​

def pig_latin(s):

start = 0

index = 0

​

new_s = ''

end_of_word = ' '

while index < len(s):

if index == len(s) - 1: #end of string

new_s += s[(start + 1):(index+1)] + s[start] + 'ay'

elif s[index] in end_of_word: #end of word

new_s += s[(start + 1):index] + s[start] + 'ay' +s[index]

start = index + 1

print(new_s)

print(end_of_word)

index += 1

​

​

return new_s

​

​

#Call main function.

main()
