python ipycytoscape 通过 id 访问一个节点

Question

假设我有一个 ipycytoscape 图如下：

railnet= '''{
    "nodes": [
        {"data": { "id": "BER", "label":"HBf BER", "classes":"east"}},
        {"data": { "id": "MUN", "label":"HBf MUN", "classes":"west"}},
        {"data": { "id": "FRA", "label":"HBf FRA", "classes":"west"}}
        ],
    "edges": [
        {"data": { "id": "line1", "source": "BER", "target": "MUN","label":"200km/h"}},
        {"data": { "id": "line2", "source": "MUN", "target": "FRA","label":"200km/h"}},
        {"data": { "id": "line3", "source": "FRA", "target": "BER","label":"250km/h" }}           
    ]
  }'''

railnetJSON = json.loads(railnet)
ipycytoscape_obj3 = ipycytoscape.CytoscapeWidget()
ipycytoscape_obj3.graph.add_graph_from_json(railnetJSON, directed=False) # I am telling I dont want directions
ipycytoscape_obj3

如何轻松访问具有id的节点？[=13=]

这不起作用：

ipycytoscape_obj3.graph.nodes['BER']. # --> wrong

Answer 1

这是因为id信息在数据里面。我没有测试它，但也许 nodes['data']['BER'] 会起作用？您可以检查此 example 以获得更复杂的 edge/node 交互。检查此笔记本上的 Pandas 会话。和往常一样，随时在 repo 上打开一个问题。谢谢！
