Triple quoted strings are often a poorer solution.

   1) to avoid breaking up the indentation structure, triple quoted
      strings must either have lots of extra white space or must be
      defined globally.  If globally, subroutine level parameter
      substitution is awkward.
   2) Parameter substitution is very awkward for long blocks of

A common idiom I run up against is defining html in which the user may have 
already entered a value.  So, one might find:

         html += "<input type=text name=xyz value=%s>" % previous("xyz")

and where it is understood that previous() reads the invoking URL for the 
xyz= parameter value.

Doing this in a long triple string is ugly.
