title: How to create an 'empty if statement' in python
body: <p>It's very common in C: hacking 'empty if statement' like this:</p>
  
  <pre><code>if(mostlyhappencondition)
      ;#empty statement
  else{
      dosomething;
  }
  </code></pre>
  
  <p>It's working in Python? I mean, can we improve the app's performance by using that? I'd also like to know why.</p>
