title: how to access rows in csv file
body: <p>im trying to get the value of the first and the thirs row in a csv file.
  my approach gives me the first and the 3rd character of the first row. instead of the fields in row 1 and 3. Would be great if someone could give me a tipp what im doing wrong!</p>
  
  <pre><code>lang_tags = []
  tweets = []
  #open and read csv file
  with open("tweet-corpus.csv", "r") as csv_file:
  reader = csv.DictReader(csv_file)
  for row in csv_file:
      lang_tags = row[0]
      tweets = row[2]
      for lan in lang_tags:
          print("lang: ", lang_tags)
          print("tweet: ", tweets)
  </code></pre>
