To expand on that: Libusrp isn't compatible to any modern USRP, and if you've got code from that era: Reimplement it in modern GNU Radio, mostly. You can't hope to copy much of that, because the last version of GNU Radio to contain libusrp was I think 3.4.2, and that's been obsolete since the release of GNU Radio 3.5.0, and that was 8 years ago.
Laura, a lot of your problems seem to stem from the fact that you might be having a hard time investigating Python errors yourself. Since you seem to be in need of writing Python, the time-rational thing to do is learning and practicing Python with a book or tutorial. Starting with something as large and complex as a GNU Radio transceiver application incorporating non-deterministic signals and even worse hardware is really not a promising approach in terms of investing your learning time wisely.
