title: Can I make column names all lower case upon import using pandas read_csv?
body: <p>I am parsing a payload and want to import only those columns that I am including in my model. I can easily do this in pandas using:</p>
  
  <pre><code>df = pd.read_csv(StringIO(values), delimiter=',', usecols=LIST_COLS)
  </code></pre>
  
  <p>However, my fear is that sometimes the column names (often camel case) will not match the column names in the model. Thus, prior to training my model, I converted all column names to lower case. Now, when I import my data I want to import the column names as lower to ensure everything will match up when all portions of the payload are concatenated and a prediction needs to be generated.</p>
  
  <p>I am assuming this is possible but I do not know how to do this.</p>
  
  <p>Thank you in advance.</p>
