If everything works fine, you should be able to run:
./self.py -> self counting
./sys.py -> system wide counting
These are counting-only interfaces to perf_event_open() syscall, with
libpfm4 being used to fill up perf_event_attr.
Arnaldo (acme@...) has also been working on a python interface
to perf (tools/perf/python/twatch.py in the kernel git tree). That is
a higher level interface, but doesn't lookup libpfm4.
