Ordinary python string replacement is available in the returned result:

def index()
     body = """
<html>
<head>
<title>%s</title>
</head>
<body>
%s
</body>
</html>
"""
     title = "This is the Title"
     content = "<p>This is the content</p>"
     return body % (title, content)

Or did you have something else in mind?
