title: pandas: convert a CSV series into a data frame
body: <p>I'm new to pandas so apologies for what I think is a trivial question, but I can't quite find the relevant function for this:</p>
  
  <p>I've got a file which consists of essentially 12 different data series, with the nth element of each series grouped together; i.e.</p>
  
  <pre><code>series_A_data0
  series_B_data0
  series_C_data0
  ...
  series_L_data0
  series_A_data1
  series_B_data1
  series_C_data1
  ...
  </code></pre>
  
  <p>I can import this into pandas as a single column data frame, but how can I get it into a 12-column data series?</p>
  
  <p>For reference, currently I'm doing:</p>
  
  <pre><code>data = pd.read_csv(file)
  data.head(14)
