I have got it, it works now!
in my example the double quotes were not escaped in pymol script :-)
the only (more python-oriented) question, would it be possible to
indicate chains_array for all letters A-Z (e.g. using some python
regex, rather just for A and B, chains_array = ["A", "B"], like in my
example?
