would either code analysed , fixed or point me in right direction please. many errors, overcome, others not.
program runs on raspberry pi2 , should try , ping specific ip addresses , return result.
very new programming, can tell! not sure if need ping library or can without
import sys import time pushbullet import pushbullet import serial class users(object): def __init__(self, name=none, ip=none): self.name = name self.ip = ip self.status = 'out' pb = pushbullet("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") #pushbullet id removed userlist = [] userlist.append(users("ali", "192.18.1.14")) userlist.append(users("sophie", "192.18.1.9")) userlist.append(users("tv", "192.18.1.7")) try: while true: print "checking... " + time.strftime("%a, %d %b %y %h:%m:%s", time.gmtime()) user in userlist: result = os.system ("ping -n 1 " = user.ip) oldstatus = user.status if (result == 0): #what we'll if device detected if (oldstatus == 'out'): push = pb.push_note("home pi", user.name + " home") user.status = 'in' print user.name + " home" else: #what we'll if device not not detected if (oldstatus == 'in'): push = pb.push_note("home pi", user.name + " has left") user.status = 'out' print user.name + " out" print "next check in 30 seconds" time.sleep(30) except (keyboardinterrupt, systemexit):
i modified code work, don't have pushbullet. compare new code previous see difference , errors
import sys import time #from pushbullet import pushbullet #import serial #you need import os import os class users(object): def __init__(self, name=none, ip=none): self.name = name self.ip = ip self.status = 'out' #pb = pushbullet("xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx") #pushbullet id removed userlist = [] userlist.append(users("notebook", "192.168.1.2")) userlist.append(users("tv", "192.168.1.4")) try: while true: print "checking...
