Clearing delayed actions for multiple devices in one command

I've been trying to rationalise and improve a lot of my sprawling python scripts, and I'm not sure if this is possible.

At present I have some action groups that run that have multiple lines for clearing device specific delayed actions, like so:

indigo.device.removeDelayedActions(monitor)
indigo.device.removeDelayedActions(lights)
indigo.device.removeDelayedActions(fan)
etc

I've been trying to find a way to get it into one single line. Most of what I've tried has failed on a syntax error. Closest I can find is:

indigo.device.removeDelayedActions(monitor),(lights),(fan)

but this doesn't seem to remove the delayed actions at all. Is this possible and if so what's the best way to do it?

I'll answer by saying that you can't, and then show you how you can.

The command indigo.device.removeDelayedActions only accepts one argument at a time, and then clears all delayed actions from the target device. The command doesn't accept collections of devices (although I believe this feature may be on the list). You can iterate over a collection of devices, which takes a couple of lines--and it's the way I'd recommend doing it because it's more Pythonic.

Code: Select all

device_list = (123456789, 987654321, 234567890)
for item in device_list:
    indigo.device.removeDelayedActions(item)

It's only three lines, and it's easy to see what's going on.

That said, you can use a little Python "trickery" using a List Comprehension, which compacts these operations down to a single line:

Code: Select all

_ = [indigo.device.removeDelayedActions(item) for item in (123456789, 987654321, 234567890)]


Still relatively easy to understand, but the above code is way more obvious. The underscore is a common way to indicate a "toss away" value which is really only necessary to make Python syntax inspectors happy (not required).

Ooooh perfect! That makes sense. I shall have a play with this later on. Much appreciated!

Dave, this forum totally need an up vote feature.

Appreciated, but not necessary. I've received a metric ton of help on these fantastic forums and I'm happy to help out when I can.

Oh and this worked perfectly. And I’ve adapted it for use with a few other lines that were similarly setup! Many thanks!
