Subtracting variable items from list

Hello!

I'm pretty new to grashopper and I'm having the following problem:

I have a circle which divides into a variable number (as seen in the screenshot). Then, a line is created from the center of the circle to the points of the divided circle. 

The problem is that I dont know how to seperate these lines into seperate lists. This needs to be scripted so that as I move the count on the division of the circle, the amount of lines changes and so do the seperate lists. 

Thank you so much
