can someone explain how to use str.index and str.find and why the following code is wrong
<p>I'm very new to python and have been trying out codewars. Some problems pretty difficult for me. What I'm trying to accomplish is,"to know the index of the vowels in a given word, for example, there are two vowels in the word super (the second and fourth letters)." I don't really understand how to use index and/or find. I need to know I can edit this code to find the positions of the vowels in any given word.</p>

<pre><code>def vowel_indices(word):
    word.index("a","i","o","u","e","y")
    word.find("a","i","o","u","e","y")
</code></pre>
