Hi

I have a list of points as shown below

points=[ [x0,y0,v0], [x1,y1,v1], [x2,y2,v2].......... [xn,yn,vn]]

Some of the points have duplicate x,y values. What I want to do is to extract the unique maximum value x,y points

For example, if I have points [1,2,5] [1,1,3] [1,2,7] [1,7,3]

I would like to obtain the list [1,1,3] [1,2,7] [1,7,3]

How can I do this in python

Thanks
