title: `from ... import` vs `import .`
body: <p>I'm wondering if there's any difference between the code fragment</p>
  <pre><code>from urllib import request
  </code></pre>
  <p>and the fragment</p>
  <pre><code>import urllib.request
  </code></pre>
  <p>or if they are interchangeable. If they are interchangeable, which is the &quot;standard&quot;/&quot;preferred&quot; syntax (if there is one)?</p>
