At first looks though, keep in mind that the Jython version is 2.7, which does not support f-strings.

Make sure those quotes are ", not “.
Also, as Jordan said, there are no fstrings in jython, you'll need to use older formatting methods

"hello {user}".format(user="Rea_Berberi")
"hello {0}".format("Rea_Berberi")
"hello %s" % ("Rea_Berberi")

and the likes.

Thank you for your answer it was so helpful. Just one more question : Is there a way to import an XML file from local env with transaction group configuration using script?
