rectangle = [(0,0,0),(0,1,0),(1,1,0),(1,0,0)]
x, y, z = zip(*rectangle)
centroid = (sum(x)/len(x), sum(y)/len(y), sum(z)/len(z))
我只会这样求，但是显然对于N维来说，这个样子太累了...
rectangle_bottom = np.array([[0,0,0],[0,1,0],[1,1,0],[1,0,0]])
centroid = sum(rectangle_bottom)/len(rectangle_bottom)
应该直接用numpy
尝试用用第三方的包 比如Pandas?
