title: Looping not happening correctly in Python
body: <p>This is my python code that works on some data (a list) that looks like:</p>
  
  <pre><code>1 Check _ VERB VB _ 0 ROOT _ _ 
  2 out _ PRT RP _ 1 prt _ _ 
  3 this _ DET DT _ 4 det _ _ 
  4 video _ NOUN NN _ 1 dobj _ _

  </code></pre>
  
  <p>The python code contains two parts: 
  1. read the lines and create the original text by collecting all the second tokens in the lines above.
  2. create word tags that look like: <code>{'pos_tag': 'NNP', 'position': '13', 'dep_rel': 'appos', 'parent': '12', 'word': 'TEAMWALMART'}</code> for each word.</p>
  
  <p>Python code:</p>
  
  <pre><code>for line in data:
      if line:
          tweet.append(line)
      if not line:
          original_tweet = get_original_tweet(tweet)
          word_tags = get_word_tags(tweet)
          new_json_object['text'] = original_tweet
          new_json_object['tags'] = word_tags
          new_json_object_list.append(new_json_object.copy())
          del tweet[:]
  print new_json_object_list
  
  def get_original_tweet(tweet_lines):
  tweet_words = []
  for line in tweet_lines:
      tweet_words.append(line.split()[1])
  original_tweet = ' '.join(tweet_words)
  return original_tweet
  
  def get_word_tags(tweet_lines):
  word_tags = {}
  word_tags_list = []
  for line in tweet_lines:
      words = line.split()
      word_tags['word'] = words[1]
      word_tags['position'] = words[0]
      word_tags['pos_tag'] = words[4]
      word_tags['dep_rel'] = words[7]
      word_tags['parent'] = words[6]
      word_tags_list.append(word_tags.copy())
      word_tags.clear()
  return word_tags_list
  </code></pre>
  
  <p>This code works fine but does that only on the first set of lines i.e. till line 13 in the data. It is ignoring the second tweet. I don't know what I am missing. The code seems correct to me. Can someone help me debug this please?</p>
