An adjacency list representation for a graph associates each vertex in the graph with the collection of its neighboring vertices or edges. There are many variations of this basic idea, differing in the details of how they implement the association between vertices and collections, in how they implement the collections, in whether they include both vertices and edges or only vertices as first class objects, and in what kinds of objects are used to represent the vertices and edges.

* An implementation suggested by [[Guido van Rossum]] uses a [[hash table]] to associate each vertex in a graph with an [[array data structure|array]] of adjacent vertices. In this representation, a vertex may be represented by any hashable object. There is no explicit representation of edges as objects.<ref>{{cite web
