title: How to write list to specific location in CSV file?
body: <p>Week over week, I want to be able to write the contents from a list I have to a CSV file. Essentially, I need to find a way to tell Python that if there is content in Column A, write the content in Column B, and so on and so forth because I want to write to the same file week over week. Here is what I have so far.</p>
  
  <pre><code>content = [1, 2, 3]
  csvfile = "my/file/path"
  column = zip(content)
  with open(csvfile, 'a') as output:
      writer = csv.writer(output, dialect = "excel")
      for item in content:
          writer.writerow(item)
  </code></pre>
  
  <p>When I run this twice, my content is appended to the bottom of the column and not a new column. Is my error in my specified mode? W truncates and R is only for reading so I am at a loss. </p>
  
  <p>Here is how it looks when run twice:</p>
  
  <pre><code>Column A
  1
  2
  3
  1
  2
  3
  </code></pre>
