I realized there is much to learn about Python Scripting Tags.
Where are the global variables for the Python Scripting Tags documented?
By reading other posts/examples, I understand that "op" and "doc" are global variables, but I did knot know there was a global function like message(msg_type, data) : available in a scripting tag.
I do not understand how message(msg_type, data) works in the scripting tag. How is it getting called? Is it like a virtual method in c++? Are there other functions like this available?

The Python documentation is currently lacking information on Python scripting features (tags, scripts, XPresso node etc).
main() in a Python tag is the same as TagData::Execute() and the available global variables are:
doc : the host document of the tag.
flags : the execution flags.
priority : the execution priority in the pipeline (EXECUTIONPRIORITY_INITIAL, EXECUTIONPRIORITY_ANIMATION, EXECUTIONPRIORITY_GENERATOR etc).
op : the Python tag.
bt : the calling thread.
tp : the TP master system for the host document if there's one.
message(id, data) in a Python tag behaves the same as TagData::Message().
It receives the data as Python dictionaries with the entries matching the names used in the C++ API for the structure members.
The available global variables are the same as in main() except that flags and priority does not make sense in message().

Thank you Yannick. This is solved.
