title: Extract the index of the first vowel in a string
body: <p>I'm trying to find any vowels that comes first from the word. Output should be same with the output of the find() function.</p>
  
  <p>So, for example,</p>
  
  <p>from "python", output should be "4" ("python".find("o") is 4)</p>
  
  <p>from "stock", output should be "2"</p>
  
  <p>from "overflow", output should be "0"</p>
  
  <p>from "styling", output should be "4" ("styling".find("i") is 4)</p>
  
  <p>Actually What I am really trying to do is to remove vowel that comes first,</p>
  
  <pre><code>    while 0 != 1:
       if word[x] in 'aeiou':
         word = word[x]+word[x+2:]
         x = x+1
      else: x = x+1
  </code></pre>
  
  <p>This is what I have been trying so far, but it causes "IndexError: string index out of range"</p>
