优雅地访问networkx中的边缘属性

确实是这样的情况：要访问 networkx 中的边缘属性，下面尴尬的第三种形式是必要的，并且更简洁的前两种形式的任何变体都行吗？

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']

Use data=True https://networkx.github.io/documentation/latest/reference/generated/networkx.Graph.edges.html:

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'])

prints

4.7
5.8
