Assuming you have read and practiced the 2 chapters on ZPT in the Zope
book I would also recommend peterbe's "DTML2ZPT Conversion examples",
even if you have never done DTML, these are a collection of common code

After that keep in mind that anything complicated enough to need 
"python:" in a TAL statement should likely be moved out to a python
method. (That could be either a python script through the ZMI, or even
better a method of your filesystem based python product.) The results of
the python method can then be placed in the option space and accessed
very easily from the ZPT. A common usage scheme is to always call the
python method through the web, which assembles all needed data and then
returns the ZPT with the data as parameters.

Have fun!
