如何获取Networkx图的边属性列表

import networkx as nx

# 创建一个有向图
G = nx.DiGraph()

# 添加节点和边以及边属性
G.add_edge('A', 'B', weight=3)
G.add_edge('B', 'C', weight=4)
G.add_edge('C', 'D', weight=2)

# 获取边属性列表
edge_attributes = []
for u, v, attr in G.edges(data=True):
    edge_attributes.append((u, v, attr))

# 打印边属性列表
for edge in edge_attributes:
    print(edge)

('A', 'B', {'weight': 3})
('B', 'C', {'weight': 4})
('C', 'D', {'weight': 2})
