title: How to add a character in a string after each vowel using python 3
body: <p>I'm trying to write a program that takes in a string(sentence) and after each vowel it adds a letter for example: "Jon" becomes "Jofon". I thought doing it with for loops maybe(certainly) there is a better way.
  Here it's what I tried so far:</p>
  
  <pre><code>sen="Jon"
  newString=""
  
  
  for letter in sen:
      if letter == "a" or letter == "e" or letter == "i" or letter == "o" \ 
      or letter == "u" or letter == "y":
          newString+=letter+"f"+letter
  
  
  print(newString)
  </code></pre>
  
  <p>It seems to add the letter "f" only to vowels leaving consonants out giving me this result:</p>
  
  <pre><code> ofo
  </code></pre>
