[Tutor] Executing Python from TCL

[Karim]

Hello Tutors,

I want to know if there are modules or whatever to execute
python functions inside TCL.
These functions should returns python lists as TCL lists and
Python dictionary as TCL Hash tables.

Existing (opensource) tools, packages are welcome!
I want to avoid to do it myself (anyway I don't have
any idea how to do it :o) )

In fact, I develop parser for xml using xml.etree.ElementTree
and another team which develop in TCL need to access it via
an API I should do. Great Challenge.

Regards
Karim
