title: A453 Task 1 help while true loop
body: <p>I trying to make a loop where instead of ending the program when the word is not found in the sentence it will ask to restart the program. Here is my code:</p>
  
  <pre><code>UserSen = input("Please type in a sentence without punctuation: ") #This will allow the user to input a sentence
  UserSen = UserSen.lower()  #This will covert the whole sentence to lower case
  UserSen = str.split(UserSen)   #This will return all the words in the UserSen as a list using str. as a separator
  
  Word_To_Find = input("Please enter a word you want to search for in the sentence: ")  #This will allow the user to input a word to find
  Word_To_Find = Word_To_Find.lower()  #This will covert the word to be searched into lower case
  
  Position = []  #Variable position is declared so it can be used later in the search part (for loop)
  Sentence_length = (len(UserSen))  #Measure length of sentence
  
  while True:
      while True:
          if Word_To_Find not in UserSen: #If the word to search is not in sentence
              print ("Error this word: ",Word_To_Find,"isn`t in the sentence" )#Display error message if word is not in the sentence
              answer = raw_input('Run again? (y/n): ')
               if answer in ('y', 'n'):
                  break
              print ("Invalid input")
          if answer == ("y"):
              continue
          elif:
              print ("Goodbye")
  else: # But if the word is found starts another iteration
      for i in range(0,Sentence_length): # Range will generate sequences of numbers in the form of a list and select the position withing the sentence and store it in the (i)ndex.
          if UserSen[i] == Word_To_Find: #if the index is equivalent to the word
              Position.append(i+1) # this will fill the empty variable i declared earlier with position(s) as this will add the word to the position list
  print ("Search successful. The word",Word_To_Find,"' has been found in position:",Position) # This will display the position of the word if the word is found
