Per ricordarsi come estrarre le info:
Python 3.4.2 (default, Oct 19 2014, 13:31:11) [GCC 4.9.1] on linux Type "help", "copyright", "credits" or "license" for more information. >>> var = "/I/Casa1/Piano2/Stanza4/Message" >>> var.split() ['/I/Casa1/Piano2/Stanza4/Message'] >>> var.split("/") ['', 'I', 'Casa1', 'Piano2', 'Stanza4', 'Message'] >>> var.split("/")[1] 'I' >>> var.split("/")[2] 'Casa1' >>> var.split("/")[3] 'Piano2' >>> var.split("/")[4] 'Stanza4' >>> var.split("/")[5] 'Message'
>>> var = "/I/Casa1/Piano2/Stanza4/Message" >>> while (var != "/"): ... #print(var) ... print(os.path.basename(var)) ... var=os.path.split(var)[0] ... Message Stanza4 Piano2 Casa1 I >>>
Ho controllato, sembra che mosquitto scriva senza il primo backslash, quindi:
>>> var = "I/Casa1/Piano2/Stanza4/Message" >>> while (var != ""): ... #print(var) ... print(os.path.basename(var)) ... var=os.path.split(var)[0] ... Message Stanza4 Piano2 Casa1 I >>>
