/home/brent/catkin_ws/src/beginner_tutorials/scripts/add_two_ints_server.py: line 4: import: command not found
/home/brent/catkin_ws/src/beginner_tutorials/scripts/add_two_ints_server.py: line 6: syntax error near unexpected token (' /home/brent/catkin_ws/src/beginner_tutorials/scripts/add_two_ints_server.py: line 6: def handle_add_two_ints(req):'
