I only use a tiny subset of DTML's capabilities, and farm out to Python
for any serious computing.  But that does not mean that DTML is useless.
It is very good, but use it for its strengths, which are to format html
output, and to orchestrate the sending of data to the actors that are
well-suited to deal with it.

For example, do not try to have a Python script create HTML for you.
Instead, let it return, say, a Python list or dictionary, and have DTML
produce the HTML from that - a perfect division of labor.

Cheers,
