Hi @Jvos,
First of all, (no worry at all) I would like to remind you to read How to Post Questions especially the part about categories.
Since your topic is related to Cinema 4D please next time create a topic within cinema 4d development. (I've moved it).
Regarding your issue, pretty much all parameters in Cinema 4D are stored in a BaseContainer.
A BaseContainer is a dictionary which links an ID (Int) to a Data.
When you are doing Object[Something] you access the value within this BaseContainer.
If you write in the console c4d.REDSHIFT_LIGHT_PHYSICAL_INTENSITY, it will print you the ID of this parameter.
Then to get the value of a parameter which is stored in the object's BaseContainer, you don't have to pass a string, but the ID, which is registered with a SYMBOL NAME because it's easier to remember than an arbitrary number (In some case there is no SYMBOL equivalent for an ID).
So as @mikeudin suggested the eval function is the right way to go, or you can directly store the ID in your list.
attributes = [c4d.REDSHIFT_LIGHT_PHYSICAL_INTENSITY, c4d.REDSHIFT_LIGHT_PHYSICAL_EXPOSURE]
Finally, there is no official C4D slack/discord or chat.
Cheers,
Maxime.
