# networkx.algorithms.distance_measures.eccentricity¶

eccentricity(G, v=None, sp=None)[source]

Returns the eccentricity of nodes in G.

The eccentricity of a node v is the maximum distance from v to all other nodes in G.

Parameters
• G (NetworkX graph) – A graph

• v (node, optional) – Return value of specified node

• sp (dict of dicts, optional) – All pairs shortest path lengths as a dictionary of dictionaries

Returns

ecc – A dictionary of eccentricity values keyed by node.

Return type

dictionary
