title: sqlalchemy,creating an sqlite database if it doesn't exist
body: <p>I am trying out sqlalchemy and i am using this connection string to connect to my databases</p>
  
  <pre><code>engine = create_engine('sqlite:///C:\\sqlitedbs\\database.db')
  </code></pre>
  
  <p>Does sqlalchemy create an sqlite database for you if one is not already present in a directory it was supposed to fetch the database file?.</p>
