title: from ... import OR import ... as for modules
body: <p>Should I use</p>
  
  <pre><code>from foo import bar
  </code></pre>
  
  <p>OR</p>
  
  <pre><code>import foo.bar as bar
  </code></pre>
  
  <p>when <strong>importing a module</strong> and and there is <strong>no need/wish for changing the name</strong> (<code>bar</code>)?  </p>
  
  <p>Are there any differences? Does it matter?</p>
