I need to run it with Jython interpreter, please provide support to resolve this issue.

Hi, I am sorry to say, that there is no solution for that issue.
Jython is 2.7 only and DataDriver is Python 3.6 or newer only.

I am sorry to say.

I would recomment to use Java remote Libraries instead of using Jython.
But that is a different topic.

Thank you for your reply and valuable information. I will try with your suggestion.
