Clever example and manageable.  Not shown is the invocation of getHeader() 
where the actual parameter values are defined.  This contrived example 
separates definition and use.  I think something like

       html += "<title>%s</title>" % ht_obj.param("title")

has better locality by bringing definition and use closer together on same 
line (or two lines).

Synthesizing this discussion,

         title = ht_obj.param("title") #extract string from URL
        ....
        html = """\
               ...
               <title>%(title)s</title>
               ...
               """

looks ok to me.  It does not allow piecing together strings conditionally 
at run time but it does a fine job of expressing fixed strings with 
substitutions.
