title: Set properties of multiple QLineEdit using a loop
body: <p>I was wondering if it is possible to set multiple <code>setFixedHeight()</code> properties using a for loop:</p>
  
  <pre><code>for num in range(1, 6):
      self.LineEdit[num].setFixedHeight()
  </code></pre>
  
  <p>currently I have twelve QLineEdit boxes</p>
  
  <p>LineEdit1, LineEdit2, ... , LineEdit12 and I'm hoping to do this with less code. I tried the above method, and it did not iterate through the LineEdit boxes as I had expected. Would <code>self.LineEdit[num]</code> only work for a list?</p>
