ros2 python run time dependencies

Hi

I am using Ubuntu 18.04 and trying to determine run time dependencies for the python demo talker node. previously for cpp demo node after sourcing the work space i just ran

ldd ./install/demo_nodes_cpp/lib/demo_nodes_cpp/talker

It gave me all the shared libraries (.so) ..I just copied and pasted in another Ubuntu 18.04 system and its working as expected.

I would like to reproduce the same with the python demo talker node..except for that its a text file in the install directory..

Any suggestions on how to proceed ?

Thanks
