How do I specify the OBIS to read via Gurux with Python

Hi. I have Gurux for Python, and I'm trying to read an electric meter via DLMS.
The command that I put in the command line is: [python .\main.py -r sn -S COM7 -d DLMS -i HdlcWithModeE] and it works but it makes a query for every OBIS possible.
I know that the parameter -g is for specifying the OBIS, and i have MAP110 (official program for reading this Landis+Gyr meter) in which I'm able to see what OBIS I have to ask for (1-1:1.8.0 for example, as the Image shows), but I don't know how to translate that way of referring to the OBIS to the python's program "language". What I know is that the parameter has to be one or more OBIS, separated by a ';' and every OBIS needs to have 2 values separated by ':'. For example: 1:8;3:8

Does someone know how could I read the OBIS that the Image shows with the Python program?

Thanks for reading
