Function get_node_data

python/graphscope/nx/classes/cache.py:447–487

Returns the attribute dictionary of node n. This is identical to `G[n]`. Parameters ---------- n : nodes Returns ------- node_dict : dictionary The node attribute dictionary. Examples -------- >>> G = nx.path_graph(4) # or DiGraph etc >>> G[0]

(graph, n)

    Parameters
    ----------
    n : nodes

    Returns
    -------
    node_dict : dictionary
        The node attribute dictionary.

    Examples
    --------
    >>> G = nx.path_graph(4)  # or DiGraph etc
    >>> G[0]
    {}

    Warning: Assigning to `G[n]` is not permitted.
    But it is safe to assign attributes `G[n]['foo']`

    >>> G[0]['weight'] = 7
    >>> G[0]['weight']
    7

    >>> G = nx.path_graph(4)  # or DiGraph etc
    >>> G.get_node_data(0, 1)
