title: error accessing dataframe pandas
body: <p>I am new to Python / pandas Dataframe and to programming at all, but I can't figure out why I have an error:</p>
  
  <p>I have a Dataframe named closes that have a column named ISP.MI that I need to access to perform operations.</p>
  
  <p>If I run the code:</p>
  
  <pre><code>    `print(closes['ISP.MI][0])`
  </code></pre>
  
  <p>I get the correct value.</p>
  
  <p>If I run the code</p>
  
  <pre><code>Name = ['ISP.MI']
  print(closes[Name][0])
  </code></pre>
  
  <p>I get an error. What am I doing wrong?</p>
