[Example request] The most basic way to turn an individual, specific light on and off · Issue #185 · mclarkk/lifxlan

I've been struggling with this for hours, i'm not a python dev, i'm just trying to control my lights with my linux pc #!/usr/bin/env python import sys from lifxlan import LifxLAN def main (): lan =...

cross-posted from: https://lemmy.ml/post/13397153

I’m just trying to control my smartlights with a script, it seems to be having a lot of problems, I really don’t know what I’m doing, i’d appreciate any help I can get

Once I have a script that can individually turn lights on/off i can edit the rest myself, I just can’t get the base functionality working.

    I saw you already solved your own issue. Just want to make sure you understand what the actual issue was and why.

    In order to use a class/function, such as Light(), the interpreter running your script needs to know what that class/function does. To do that, either you need to have defined it in your code (like you did with your main function) or you need to have imported it from from a another source like lifxlan where it is defined. In your original script, you imported the class LifxLAN, though as you discovered, you forgot to import the class Light as well. I’m assuming those are classes, btw, from both context and the fact that they follow the python naming convention (functions and variables are all_lower_case, Classes are CapitalizedWords, and CONSTANTS are ALL_CAPS)

    Additionally, instead of importing each class, you could have also imported the entirety of the lifxlan library by changing your import statement to import lifxlan. I’m not recommending you do that. It’s not best practice to import more than you need and it can cause issues if what you’re importing is not just a library but also executes code. But, if you did import the whole library, that would have imported all of the classes and functions in lifxlan including both LifexLAN and Light. You could then create objects of those classes or call those functions by prefixing the library name to their name. For example, lifxlan.Light().

      Yeah, my real issue was that I erroneously assumed

      from lifxlan import LifxLAN

      WOULD import the Light function, but of course, it does not, I didn’t realize that when you do a from import you’re just importing a single specific command and not the whole library, and just used it like it was in the examples they gave, but thank you for the comment and this community is awesome, just that you were willing to write that all that out just to help me understand is incredibly kind, thank you!
