優先訪問網絡中的邊緣屬性x

Question

確實如此，要訪問networkx中的邊緣屬性，需要下面的尷尬第三種形式，並且沒有更多苗條前兩種形式的變化會做什麼？

import networkx as nx 

G = nx.Graph() 
G.add_edge(1, 2, weight=4.7) 
G.add_edge(3, 4, weight=5.8) 

# for edge in G.edges(): 
#  print edge['weight'] 
# 
# for edge in G.edges(): 
#  print G[edge]['weight'] 

for edge in G.edges(): 
    print G.edge[edge[0]][edge[1]]['weight'] 

Answer 1

使用data=True：

import networkx as nx 

G = nx.Graph() 
G.add_edge(1, 2, weight=4.7) 
G.add_edge(3, 4, weight=5.8) 

for node1, node2, data in G.edges(data=True): 
    print(data['weight']) 

打印

4.7 
5.8
