title: Pandas: create named columns in DataFrame from dict
body: <p>I have a dictionary object of the form:</p>
  
  <pre><code>my_dict = {id1: val1, id2: val2, id3: val3, ...}
  </code></pre>
  
  <p>I want to create this into a DataFrame where I want to name the 2 columns 'business_id' and 'business_code'.  </p>
  
  <p>I tried:</p>
  
  <pre><code>business_df = DataFrame.from_dict(my_dict,orient='index',columns=['business_id','business_code'])
  </code></pre>
  
  <p>But it says <code>from_dict</code> doesn't take in a columns argument.</p>
  
  <blockquote>
    <p>TypeError: from_dict() got an unexpected keyword argument 'columns' </p>
