title: Filtering a CSV file column and then export it to excel
body: <p>I have a huge dataset in a csv file and want to filter one of the columns if they are equal to 334 and then export all the dataset into a excel file! when the file is filtered it can be used in a excel file. so far I could manage to write this code but I do not know how to filter the column and then export all into a excel file.</p>
  
  <pre><code>import itertools
  import csv   
  from itertools import islice
  
  with open("eee.csv", 'r') as my_file:
      reader = csv.reader(my_file)
      for row in itertools.islice(reader, 100):
           print (row)
  </code></pre>
