  <p>Ronald is filling up his dataset with new data to classify species of <em>Iris </em>flowers better. Define a function <code class="java">add_iris()</code> to help him a bit.</p> 
  <p>The parameters for each new sample include <code class="java">id_n</code> identifying a flower, <code class="java">species</code>, <code class="java">petal_length</code> and <code class="java">petal_width</code>. Apart from <code class="java">species</code>, which should be a string, all the mentioned parameters will have a numerical value: either an integer (<code class="java">id_n</code>) or a float (<code class="java">petal_length</code>, <code class="java">petal_width</code>). Collect other <strong>keyword</strong> arguments in case new features appear.</p> 
  <p>Your function should add a new key-value pair into an existing dictionary called <code class="java">iris</code>. Predictably, <code class="java">id_n</code> will serve as a key, and its value should be a dictionary with the rest of specified parameters.</p> 
  <p>For example, after calling the function for the first time <code class="java">add_iris(0, 'Iris versicolor', 4.0, 1.3, petal_hue='pale lilac')</code> the dictionary <code class="java">iris</code> will look like this <code class="java">{0: {'species': 'Iris versicolor', 'petal_length': 4.0, 'petal_width': 1.3, 'petal_hue': 'pale lilac'}}</code>. Pay attention to the last pair that represents a new feature.</p>
