WebAug 18, 2024 · In Python, an adjacency list can be represented using a dictionary where the keys are the nodes of the graph, and their values are a list storing the neighbors of these nodes. We will use this representation for our implementation of the DFS algorithm. Let’s take an example graph and represent it using a dictionary in Python. WebAn adjacency list is a hybrid between an adjacency matrix and an edge list that serves as the most common representation of a graph, due to its ability to easily reference a vertex 's neighbors through a linked list. Through the use of adjacency list, it is easy to look up a node's neighbors in constant or O (1) time.
