程式碼：節點集合

list(G.nodes(data=True))

[('repo3', {'bipartite': 'repositories'}),
 ('repo1', {'bipartite': 'repositories'}),
 ('user1', {'bipartite': 'users'}),
 ('user2', {'bipartite': 'users'}),
 ('repo2', {'bipartite': 'repositories'}),
 ('user3', {'bipartite': 'users'})]

list(G.edges())

[('repo1', 'user3'),
 ('user1', 'repo2'),
 ('user2', 'repo2'),
 ('repo2', 'user3')]

程式碼：節點集合

user1_nbrs = G.neighbors('user1')

user1_nbrs

['repo2']

user3_nbrs = G.neighbors('user3')
user3_nbrs

['repo2', 'repo1']

程式碼：節點集合

set(user1_nbrs).intersection(user3_nbrs)

{'repo2'}

set(user3_nbrs).difference(user1_nbrs)

{'repo1'}

一起來練習吧！
