(Python) Create boundary for polyline-help

Hi, looking for some help with this script. Basically I've offset a couple of rectangles a fixed distance. I want to find the boundary of the perimeter surface so I can later extrude it. I know this can be done inside Grasshopper exclusively but I want to learn how to do it in Python (ideally I'd like to create all boundary surfaces within the script but am not sure how). Thanks for any help, I'm still learning the ins and outs of Python.

Hi, that's what I was looking for, good learning experience, thanks!

a = []

for i in plot: 
offset_curve = rs.OffsetCurve(i, x, -11, 0)[0]
boun_srf = rs.AddPlanarSrf([i,offset_curve])[0]
a.append(boun_srf)

Just for my own education, what is the function of the numbers and brackets in bold, above?
