Format of edge and node weights?

Sorry I could not find any docs that can solve my question. In what format should I provide edge and node weights to `part_gragh()` ? Some example codes below.

``` python
adjacency = {\
        0:[1,2], 
        1:[0],
        2:[0]}
cuts, part_vert = part_graph(2, adjacency)
```

Is it correct to set `edgeweights={2,1,3,1}` according to the order of appearance of the edges? Thanks!
