Arrays, Got Me Confused

[Robert Rawlins - Think Blue]

Hello Guys,

Wider fragments of code don't really exists at this moment in time :-D this
is just a bit of a 'tester' class for me to get used to the methods.
Basically I'm trying to create a class that contains an array of MAC
address, these look something like this 'FD:E4:55:00:FG:A9. I want the class
to have the following methods for easy manipulation of the array.

addDevice(Address) - Pass in the MAC address and have it add it to the
array.

removeDevice(Address) - Finds a device with that address in the array and
removes it.

isFirewalled(Address) - looks for that address in the array and returns
true/false dependant on whether it finds it.

Clear() - empty the array of all its contents.

Sorry for the sloppy code so far, I'm really new to Python so it's a steep
learning curve for me, I'm by no means a programming numpty and allot of the
principles are the same, but the languages I'm used to are more robust and
vague so I don't have to define what type of data i'm storing the array and
things.

Thanks guys,

Rob

Well, also the line referencing "Self.FireArray"
is not going to work, unless there's
some global "Self" knocking around. Python is
case-sensitive.

More importantly, I suspect, is that the OP's
almost certainly looking for a Python *list*,
not an array in this case. It's hard to tell,
since we've no idea what's in the "c" which
is being passed to the array.

Robert - can you explain what you're trying to
do and/or post a wider fragment of code?
