title: Plotting CSV rows/columns simpler on Python
body: <p>I have a csv file I am trying to read. The first row in the excel/csv sheet is the column headers "Jan|Feb|Mar..." etc. Then below each column header is float data. I have the following code:</p>
  
  <pre><code>filename ='Data.csv'
  with open(filename) as f:
  csvreader = csv.reader(f)
  header_row = next(csvreader)
  Jan, Feb = [], [] .... #(and so on)
  Mar = []
  Apr = []
  May = []
  Jun = []
  Jul = []
  Aug = []
  Sep = []    
  Oct = []
  Nov = []
  Dec = []
  for row in csvreader:
      Jan.append(float(row[1]))
      Feb.append(float(row[2]))
      Mar.append(float(row[3]))
      Apr.append(float(row[4]))
      May.append(float(row[5]))
      Jun.append(float(row[6]))
      Jul.append(float(row[7]))
      Aug.append(float(row[8]))
      Sep.append(float(row[9]))
      Oct.append(float(row[10]))
      Nov.append(float(row[11]))
      Dec.append(float(row[12]))
  </code></pre>
  
  <p>How can I condense this code so I can easily plot a bar graph with the months on the x-axis and the data on the y-axis?</p>
