Writing a function that counts characters and vowels : <p>I need to write a function that counts characters and vowels from a string that a user inputs, and write a routine that calls the function and displays this:</p>

<pre><code>$ ./count_all.py
Enter some words: The sun rises in the East and sets in the West
13 letters in 47 are vowels.
</code></pre>

<p>What would be the best way to do this?</p>
