Call Class Function Using A List Of Class Objects Python

Question

I have a class that I pass various values (IP address, name, model ect) when I define the class.

At the same time I am putting these classes into a list so I can easily expand the number of devices. I want to be able to call a separate function from the class.

For example

My class looks somewhat like

class foo:
    def __init__(self, IP, Name, Model, Series):
         #Do stuff
    def getstate():
         #Do more stuff and return a value

My list looks somewhat like

Devices = {}    #I fill this up with the list of all devices elseware
ClassDevices = []

for key in Devices:
        print 'List is empty, store objects'
        ClassDevices.append(Foo(Devices[key]["IP"], Devices[key], Devices[key]["Model"], Devices[key]["Series"]))

The above seems to work but now I want to be able to get the status of each device. I have tried the following

print ClassDevices[0].getstate()

And I get an error

TypeError: object cannot be interpreted as an index

I'm new to Python so I am not even sure if what I am trying to do is possible

Full code (since it probably is easier) can be seen here

What you are trying to do is pretty simple. The main issue is that you are not iterating correctly (because you are new to Python).

You have a piece of code that looks like this:

for x in SmartHome.SenseMeDevices:
    print(SmartHome.SenseMeDevices[x].getstate())

In this case x is already an element of your list, not an index to an element.

You should instead iterate like this:

for x in SmartHome.SenseMeDevices:
    print(x.getstate())
