title: Star (*) as an argument in python function
body: <p>I was looking at the definition of the <code>glob</code> function and I noticed that the second argument was simply <code>*</code>.</p>
  
  <pre><code>def glob(pathname, *, recursive=False):
      """Return a list of paths matching a pathname pattern.
      [...]
      """
      return list(iglob(pathname, recursive=recursive))
  </code></pre>
  
  <p>What is the point of the <code>*</code>?</p>
