title: use python to write to a specific column is a .csv file
body: <p>I have a .csv file where I need to overwrite a certain column with new values from a list.</p>
  
  <p>Let's say I have the list L1 = ['La', 'Lb', 'Lc'] that I want to write in column no. 5 of the .csv file.</p>
  
  <p>If I run:</p>
  
  <pre><code>L1 = ['La', 'Lb', 'Lc']
  import csv
  with open(r'C:\LIST.csv','wb') as f:
      w = csv.writer(f)
      for i in L1:
          w.writerow(i)
  </code></pre>
  
  <p>This will write the L1 values to the first and second column.</p>
  
  <p>First column will be 'L', 'L', 'L' and second column 'a', 'b', 'c'</p>
  
  <p>I could not find the syntax to write to a specific column each element from the list. (this is in Python 2.7). Thank you for your help!</p>
  
  <p>(for this script I must use IronPython, and just the built in Libraries that comes with IronPython) </p>
