Need help with script to automate certain things

I need to animate the visibility of objects in a scene. Specifically, the goal is to keep the first object visible from frame 0 to frame 36, the second object from frame 37 to frame 71, and so on. I have successfully created a list to store the objects, but I need guidance on implementing the visibility animation.

Additionally, I want to configure the animation of a camera object moving along a path. Specifically, I need to set the “Out of Range” type of the percentage controller to “Cyclic” so that the animation seamlessly loops. I would like to achieve this configuration programmatically using a script.
