I am customizing the following code This is the input

(Is there a line count at the start of the file?)
sign = -1
area = sum( map( lambda x: x.area, rectangles) )
for i in range(2,len(rectangles)+1):
for rects in combinations( rectangles, i ):

rects = rects[1:]
for rectangle in rects:

for otherR in intersections:

print intersections

Where I need to change the code to output all overlapping rectangles and its co
ordinates?
I tried your code and got a bunch of output, mostly [] lines like this:
[]
[]
[]
[]
[]
[[Point(x=1.6, y=1.6),Point(x=3.4, y=3.1)]]
[]
[]
[[Point(x=1.6, y=1.6),Point(x=3.4, y=3.1)]]
[]
What output did you expect for this input data?
(I plotted your data and out of five rectangles A,B,C,D,E (not in the
same order as your data), then A and B overlap, as do C and D, while E
is by itself.
Did you want the output to be, for example, A and B, with the
coordinates of the common region, and the same for C and D?
What happens if 3 or more rectangles overlap?
What about if A overlaps B; B overlaps C; C overlaps D; and D overlaps
A? Suppose then that all those are contained within E?
You need some specifications. I assume all rectangles are horizontally
aligned (they have to be with just 4 coordinates), and the input data
normalised so that the top-left corner appears first.)
