title: How much slower python classes are compared to their equivalent functions?
body: <p>When I started learning Python, I created a few applications just using <strong>functions</strong> and <strong>procedural</strong> code. However, now I know <strong>classes</strong> and realized that the code can be much readable (and subjectively easier to understand) if I rewrite it with classes.</p>
  
  <p>How much slower the equivalent <strong>classes</strong> may get compared to the <strong>functions</strong> in general? Will the initializer, methods in the classes make any considerable difference in speed?</p>
