从networkx图中提取边缘数据

import networkx as nx

# 创建一个有向图
G = nx.DiGraph()

# 添加节点
G.add_node(1)
G.add_node(2)
G.add_node(3)

# 添加边缘
G.add_edge(1, 2, weight=0.5)
G.add_edge(2, 3, weight=2.0)

# 提取边缘数据
edges = G.edges(data=True)

# 遍历边缘数据
for edge in edges:
    source_node = edge[0]
    target_node = edge[1]
    edge_attributes = edge[2]
    
    print("起始节点:", source_node)
    print("结束节点:", target_node)
    print("边的属性:", edge_attributes)
    print("---")

起始节点: 1
结束节点: 2
边的属性: {'weight': 0.5}
