Perhaps you should consider an alternative approach. You could consider it a graph, and you could use Networkx or Scipy to work with them (provided it actually works well with the rest of your problem) In the case of Scipy, the graph is described by its adjacency matrix, and you just want to delete a row and a column. But, in any case, not knowing at all what is your overall project, renumbering nodes is not something one has to usually do when working with graphs, except for final results. The labels are that, labels, with no further meaning. /David.
