在NetworkX (python)中迭代(重新)命名节点和边属性

import networkx as nx

# 创建一个有向图
G = nx.DiGraph()

# 添加节点
G.add_node(1, name='Node 1')
G.add_node(2, name='Node 2')
G.add_node(3, name='Node 3')

# 迭代命名节点属性
new_names = {'Node 1': 'New Node 1', 'Node 2': 'New Node 2', 'Node 3': 'New Node 3'}
for node in G.nodes():
    G.nodes[node]['name'] = new_names[G.nodes[node]['name']]

# 打印节点属性
for node in G.nodes():
    print(node, G.nodes[node]['name'])

import networkx as nx

# 创建一个有向图
G = nx.DiGraph()

# 添加边
G.add_edge(1, 2, weight=0.5)
G.add_edge(2, 3, weight=0.8)
G.add_edge(3, 1, weight=0.2)

# 迭代命名边属性
new_weights = {0.5: 1.0, 0.8: 2.0, 0.2: 3.0}
for edge in G.edges():
    G.edges[edge]['weight'] = new_weights[G.edges[edge]['weight']]

# 打印边属性
for edge in G.edges():
    print(edge, G.edges[edge]['weight'])
