body: <p>I'm trying to join htm header with the body and trailer like this</p>
  
  <pre><code>    message1 = """&lt;html&gt;
  &lt;head&gt;&lt;/head&gt;
  &lt;body&gt;&lt;p&gt;"""
  message2 = 'Hello World!'
  message3 = """&lt;/p&gt;&lt;/body&gt;
  &lt;/html&gt;"""
  
  html_message = join(message1,message2,message3)
