title: How to import from Qt:: namespase (Qt5, Python3.x)?
body: <p>For my application, I need to set some widget parameters like alignment (<code>Qt::AlignBottom</code>) and others. But I can't import them (other PyQt5 stuff imports without any issues).</p>
  
  <p>Using this code</p>
  
  <pre><code>from PyQt5 import Qt
  
  progressBar = QProgressBar(splash)
  progressBar.setAlignment(Qt.AlignBottom)
  </code></pre>
  
  <p>I got the following error:</p>
  
  <pre><code>Traceback (most recent call last):
    File "run_app.py", line 50, in &lt;module&gt;
      runSemApp(sys.argv)
    File "run_app.py", line 32, in runSemApp
      progressBar.setAlignment(Qt.AlignBottom)
  AttributeError: 'module' object has no attribute 'AlignBottom'
  </code></pre>
  
  <p>And using this one works:</p>
  
  <pre><code>from PyQt5.Qt import *
  
  progressBar = QProgressBar(splash)
  progressBar.setAlignment(Qt.AlignBottom)
  </code></pre>
  
  <p>Though I have a working solution, I would like to import only <code>Qt.AlignBottom</code> and not <code>*</code>. Also, why doesn't <code>Qt.AlignBottom</code> work with <code>from PyQt5 import Qt</code>?</p>
