Getting areas, length of sides and neighborhood of Voronoi cells in Python

In the Mathematica Stack Exchange there is this question about finding the area, perimeter and number of sides of Voronoi cells. I want to know if there is any library in Python that allows one to, given a square and N points inside it, get the areas, the length of each side and the neighborhoods of all Voronoi cells in the Voronoi diagram generated by the points. By neighborhood of a cell, I mean a list of which cells share a side with it.
