title: How to insert 3 blank lines in python after each grade
body: <p>I'm combining to different csv files into a single new csv file. The first csv file is of absentees and in the new csv file I want 3 blank lines to be entered AFTER the absentee data.
  In the second csv file is the list of present people from each grade. I want to  insert 3 blank lines AFTER each grade.</p>
  
  <p>The code I have so far is:</p>
  
  <pre><code>import csv
  with open('Inschool.csv') as f:
      reader =  csv.reader(f)
      in_school = list(reader)
  with open('notinschool.csv') as f:
      reader =  csv.reader(f)
      not_in_school = list(reader)
  for grade, name, status, hr_teacher in not_in_school:
      print grade, name, status, hr_teacher
  for grade, name, status, hr_teacher in in_school:
      print grade, name, status, hr_teacher
  iFile = open('Inschool.csv',)
  reader = csv.reader(iFile)
  IFILE = open('notinschool.csv')
  READER = csv.reader(IFILE)
  oFile = open('combined.csv','wb')
  writer = csv.writer(oFile, delimiter='|', quoting=csv.QUOTE_ALL)
  for row in READER:
      writer.writerow(row)
      writer.writerow([])
  for row in reader:
      writer.writerow(row)
  </code></pre>
