---------------

    For example, let's suppose you want to write a web page which
    displays a representation of the famous "Fibonacci
    sequence":http://www.mathacademy.com/pr/prime/articles/fibonac/index.asp.
    You would not want to write the program that actually makes the
    calculation of the Fibonacci numbers by writing DTML.  It could be
    done in DTML, but the result would be difficult to understand and
    maintain.  However, DTML is perfect for describing the page that
    the results of the Fibonnacci calculations are inserted into.  You
    can "call out" from DTML to Script (Python) objects as necessary
    and process the results of the call in DTML.  For example, it is
    "trivial in
    Python":http://www.python.org/doc/current/tut/node6.html (search
    for the word Fibonacci on this page) to implement a Fibonacci
    sequence generator, and trivial in DTML to create a dynamic web
    page which shows these numbers in a readable format.  If you find
    yourself creating complex and hard-to-understand logic in DTML,
    it's likely time to explore the the Zope features which allow you
    to script "logic" in Python, while letting DTML do the
    presentation "dirty work".

       we can see the way too calculate the Fibonacci number in pythin. can tou show here formatting of it in DTML?
