title: How do I read/parse all yaml files in a directory?
body: <p>Well, I am trying to read a collection of <code>utf-8</code> yaml files in a directory with <code>python 2.7</code> and <code>pyyaml</code>. 
  I tried to use <code>os.listdir(os.getcwd())</code>, but it actually returns a list of files and I need to read the files and exhibit the content (key, value).
  The directory only has yaml files and pyyaml library is already installed.</p>
  
  <p>All the content of the yaml files are similar to this:</p>
  
  <pre><code>fruits:
   - bananas
   - apples
   - grapes
  </code></pre>
  
  <p>Can anyone help me?</p>
