I'm not sure what "action" is in this context.  In a typical case in POX, you'd 
be appending to the action list of a an ofp_packet_out or ofp_flow_mod ("msg"):
msg.actions.append(of.ofp_action_output(port=...))
msg.actions.append(of.ofp_action_output(port=...))

Or just:
msg.actions = [ of.ofp_action_output(port=1), of.ofp_action_output(port=2) ]
