I have a nice python class and I need to instantiate the class, and then I need to run a specific function in that class. Basically, we are using a language like PHP to run shell commands. Here is my python class (lighting.py):
#!/usr/bin/python
from phue import Bridge
from pprint import pprint
import time
import logging;logging.basicConfig()
class OfficeLights(object):
#Basically Python's constructor
def __init__(self):
self.ip = 'xx.xx.xx.xx'
self.username = 'xxxxx'
self.lightInterface = Bridge(self.ip, self.username)
self.lightInterface.connect()
self.lightInterface.get_api()
self.lightInterface.create_group('Office', [1,2,3,4])
self.cycles = 15
self.period = 1
self.evvDev = 'http://dev.google.com'
self.evvStage = 'http://staging.google.com'
#List all the lights available to play with
def listLights(self):
lights = self.lightInterface.lights
for l in lights:
print(l.name)
#Generic strobe function
def strobe(self, hue, cycles):
for x in range(0, cycles):
self.lightInterface.set_group(1, 'on', True)
self.lightInterface.set_group(1, 'hue', hue)
self.lightInterface.set_group(1, 'bri', 254)
time.sleep(self.period)
self.lightInterface.set_group(1, 'on', False)
time.sleep(self.period)
#Flashing funtions, to be executed on actions
def flashRed(self):
self.strobe(0, self.cycles)
def flashGreen(self):
self.strobe(25500, self.cycles)
def flashPurple(self):
self.strobe(46920, self.cycles)
def flashPink(self):
self.strobe(56100, self.cycles)
#Check if a website is up/down based on https status headers
def is_website_online(self, host):
import httplib2
h = httplib2.Http()
resp = h.request(host, 'HEAD')
return int(resp[0]['status']) < 400
#Check EVV sites for up/down
def check_evv_sites(self):
if(self.is_website_online(self.evvDev) is not True):
self.flashRed()
if(self.is_website_online(self.evvStage) is not True):
self.flashRed()
else:
self.flashGreen()
I am trying to run the command from terminal but I only ever get the error that 'OfficeLights is not defined'? Not sure what else I need to do?
python -c 'import lighting; lights = OfficeLights(); lights.flashPurple();'

Make sure you reference the module imported or use the from method listed in the previous answer.
python -c 'import lighting; lights = lighting.OfficeLights(); lights.flashPurple();'
Additionally, the module needs to be in your project path, or the command needs to be issued from the same directory containing the module.

test sample:
└> cat hello.py
class Hello:
def hello(self):
print "hello"
└> python -c 'from hello import Hello; h= Hello(); h.hello()'
hello
└> python -c 'import hello; h= hello.Hello(); h.hello()'
hello
you can choose either import mypackage.mymodule
or from mypackage.mymodule import myclass
python -c 'from lighting import OfficeLights; lights = OfficeLights(); lights.flashPurple();'
