title: Time Complexity of operation - Python
body: <p>I was wonder what the time complexity of certain operation in python are:</p>
  
  <pre><code>x = k * l ( multiplication )
  
  x = k/l ( division )
  
  math.sqrt(y)
  
  math.pow(y,f)
  </code></pre>
  
  <p>and what is the complexity for using a while - loop.</p>
