If you are using these examples, you are learning. In learning, you don't waste your time... you use it. Some things take longer than others.

I used a lot of my time to learn using Python in OBS... A LOT.

Maybe my repository is usefull for you: https://github.com/MarioMey/obs-osc-pythonscript. It has a lot of commands ready to use... or ready to learn from. But now, I can't help you, I don't use it since pandemic. I don't even have this code installed in my system.

@contextmanager
def scene_enum(items): # _scene
    items = S.obs_scene_enum_items(items) # _scene
    try:
        yield items
    finally:
        S.sceneitem_list_release(items)     

There is indeed a problem with this code, argument should be named _scene and not items. I did test on the original script and it worked no crashes or memory leaks. I'll update the confusing line later.

I've changed the code, should be more clear. I will close the issue now, but if you have any questions or suggestions feel free to reopen it again( regarding that example).
