Example of GetRequest object usage

>>> from pysnmp.proto import v2c
>>> req = v2c.GetRequest()
>>> req
GetRequest(version=Version(1), community=Community('public'), pdu=Pdus(get_request=GetRequestPdu(request_id=RequestId(0L), error_status=ErrorStatus(0), error_index=ErrorIndex(0L), variable_bindings=VarBindList())))
>>> req['community'].set('mycomm')
>>> req['pdu']['get_request']['variable_bindings'].append(v2c.VarBind(name=v2c.ObjectName('1.3.6.1.2.1.1.1.0')))
>>> req.encode()
'0&\002\001\001\004\006mycomm\240\031\002\001\000\002\001\000\002\001\0000\0160\014\006\010+\006\001\002\001\001\001\000\005\000'
>>> req.reply()
Response(version=Version(1), community=Community('mycomm'), pdu=Pdus(response=ResponsePdu(request_id=RequestId(4L), error_status=ErrorStatus(0), error_index=ErrorIndex(0L), variable_bindings=VarBindList(VarBind(name=ObjectName('.1.3.6.1.2.1.1.1.0'), value=BindValue(unspecified=Null(None)))))))
