I repeat: The OP asked for the runlevel, not the systemd target. That should tell you that an answer involving systemd "does not make sense". To the OP: as others have said, the file /var/run/utmp contains various records, including the RUN_LVL (runlevel) record. You can find some documentation in utmp(3), including a record layout, and an values list. I don't know that python includes a standard or builtin method to parse the utmp file; to retrieve the runlevel, you may have to code your own access routine as part of your python code, or resort to invoking an external program like who(1).
