Trying to make Function loop and break if user enters nothing

Question

My function is:

vowels=('a','e','i','o','u')
prefixes=('bl','br','ch','cl','cr','dr','fl','fr','gl','gr','kl','ph','pl','sh','sl','sp','sr','st','th','tr','wh','wr')
def convertToPigLatin(word):
    first_prefix=word[0:2]
    first_letter=word[0]
    if first_prefix in prefixes:
        return word[2:]+word[0:2]+'ay'
    if first_letter in vowels:
        return word+'yay'
    else:
        return word[1:]+word[0]+'ay'

now what would I enter and where at to make it loop and break if the user enters nothing

Im not really sure what you meant, but what I understood is that you want this function to be repeatedly asked until somebody inputs nothing. Here is my answer(please correct me if i am wrong):

while True:
   x = input("convert to piglatin")
   if x == "":
       break

   print(convertToPigLatin(x))

If this isn't what you wanted please describe a little bit better in the comments. Thanks!

Empty strings are considered false, so `if not x:` is sufficient. – Mark Tolonen Mar 02 '19 at 01:20

Ok then, thank you for notifying me. I should edit this. Wow, I am learning a lot about good code practice today! :-) – Abhiraam Eranti Mar 02 '19 at 01:20
Mark Tolonen, wouldn't the program just run again and again without outputting anything? – Abhiraam Eranti Mar 02 '19 at 01:22
this is the way im trying to change it however when changing it I get a syntax error with the return command – Gage Petrick Mar 02 '19 at 01:48
