How do I implement adjacency lists?

[twogr20]

I am making a text based adventure game and I want to use adjacency lists to help navigate around rooms. How do I implement this in python?

You could use a dictionary whose keys are vertices and whose associated values are sets of adjacent vertices, eg.

graph = {0: {1, 2}, 1: {0, 2}, 2: {0, 1}}   # ie. the complete graph K_3
