Hi Marcelo,

gr.oscope_sink_f is a low level building block that handles
triggering, etc.

The high level interface that you are looking for is scopesink.scope_sink_f

See gnuradio-examples/python/usrp/usrp_oscope.py for an example, or
see the example at the bottom of gr-wxgui/src/python/scopesink.py
