title: Can I assign values in RowProxy using the sqlalchemy?
body: <p>When I want to display some data in the web, the data need makeup, and I don't know how to achieve, here is the code:</p>
  
  <pre><code>from sqlalchemy import create_engine
  
  engine = create_engine('mysql://root:111@localhost/test?charset=utf8')
  conn = engine.connect()
  
  articles = conn.execute('SELECT * FROM article')
  articles = articles.fetchall()
  
  for r in articles:
      r['Tags'] = r['Keywords']
  </code></pre>
  
  <p>It tips that: 'RowProxy' object does not support item assignment.</p>
  
  <p>What should I do for that?</p>
  
  <p>The table 'article' contains the column 'Keywords', and not contains the column 'Tags'.</p>
