title: Regular Expressions in Python for match files in a folder
body: <p>I want to match all the files in a folder using regular expressions for some reason:
  I used this: </p>
  
  <pre><code>re.compile(r'\.*$')
  </code></pre>
  
  <p>But this is also matching hidden files and temp files.
  Is there a better option?</p>
