networkx.relabel.convert_node_labels_to_integers¶

convert_node_labels_to_integers(G, first_label=0, ordering='default', label_attribute=None)[source]¶

Return a copy of the graph G with the nodes relabeled using consecutive integers.

Parameters:

G (graph) – A NetworkX graph
first_label (int, optional (default=0)) – An integer specifying the starting offset in numbering nodes. The new integer labels are numbered first_label, …, n-1+first_label.
ordering (string) – “default” : inherit node ordering from G.nodes() “sorted” : inherit node ordering from sorted(G.nodes()) “increasing degree” : nodes are sorted by increasing degree “decreasing degree” : nodes are sorted by decreasing degree
label_attribute (string, optional (default=None)) – Name of node attribute to store old label. If None no attribute is created.

Notes

Node and edge attribute data are copied to the new (relabeled) graph.
