Guido 写了一个 essay关于使用字典在 Python 中实现图形。他给出了以下示例:

Few programming languages provide direct support for graphs as a datatype, and Python is no exception. However, graphs are easily built outof lists and dictionaries. For instance, here's a simple graph (Ican't use drawings in these columns, so I write down the graph'sarcs):

A -> B
A -> C
B -> C
B -> D
C -> D
D -> C
E -> F
F -> C 

This graph has six nodes (A-F) and eight arcs. It can be represented by the following Python data structure:

graph = {'A': ['B', 'C'],
         'B': ['C', 'D'],
         'C': ['D'],
         'D': ['C'],
         'E': ['F'],
         'F': ['C']}
