title: convert Series to DataFrame
body: <p>I created a dataframe 'x' </p>
  
  <p>I wanted to create another dataframe y which consists of values of feature 'wheat_type' from dataframe x</p>
  
  <p>so i executed the code</p>
  
  <pre><code>y=X.loc[:, 'wheat_type']
  </code></pre>
  
  <p>when I ran the following command</p>
  
  <pre><code>y['wheat_type'] = y.wheat_type("category").cat.codes
  </code></pre>
  
  <p>I got following error</p>
  
  <blockquote>
    <p>'Series' object has no attribute 'wheat_type'</p>
  </blockquote>
  
  <p>on executing type(X),I got</p>
  
  <pre><code> &lt;class 'pandas.core.frame.DataFrame'&gt;
  </code></pre>
  
  <p>and on executing type(y),I got</p>
  
  <pre><code> &lt;class 'pandas.core.series.Series'&gt;
  </code></pre>
  
  <p>Is there possible way to covert y into a dataframe.If not,please tell me how to create required dataframe y from x</p>
