title: Reading rows from a CSV file in Python
body: <p>I have a CSV file, here is a sample of what it looks like:</p>
  
  <pre><code>Year:  Dec: Jan:
  1      50   60
  2      25   50
  3      30   30
  4      40   20
  5      10   10
  </code></pre>
  
  <p>I know how to read the file in and print each column (for ex. - <code>['Year', '1', '2', '3', etc]</code>). But what I actually want to do is read the rows, which would be like this <code>['Year', 'Dec', 'Jan']</code> and then <code>['1', '50', '60']</code> and so on. </p>
  
  <p>And then I would like to store those numbers <code>['1', '50', '60']</code> into variables so I can total them later for ex.:</p>
  
  <p><code>Year_1 = ['50', '60']</code>. Then I can do <code>sum(Year_1) = 110</code>.</p>
  
  <p>How would I go about doing that in Python 3?</p>
