body: <p>i've implement a class to store tweets:</p>
  
  <pre><code>class Twitter_User():
      def __init__(self,id,count=200):
          self.id = id
          self.count = count
      def get_tweets(self):
          store_tweets = api.user_timeline(self.id, count=self.count)
          simple_list = []
          for status in store_tweets:
              array = [status._json["text"], status._json["favorite_count"], status._json["created_at"],status._json["retweet_count"]]
              simple_list.append(array)
          data = pd.DataFrame(simple_list, columns=["Text", "Like", "Created at","Retweet"])
