title: Python operator that mimic javascript || operator
body: <p>I am Python newbie, so maybe don't knew if this is obvious or not.</p>
  
  <p>In Javascript <code>a||b</code> returns <code>a</code> if <code>a</code> is evaluated to true, else returns <code>b</code>. 
  Is that possible in Python other than lengthy if else statement.</p>
