Networkx：如何在具有节点属性的图形中使用out_edges（）？

Question

I use networkx library

I need to use the out_edges in a MultiDiGraph graph. When I use it in empty nodes works well:

g = nx.MultiDiGraph()
g.add_edges_from([(1,2),(3,4),(1,6)])
g.out_edges(1)   

Out:

[(1, 2), (1, 6)]

But if put attributes in nodes:

g[1]["foo"] = "fighter"

It crashes:

g.out_edges(1)
AttributeError: 'str' object has no attribute 'items'

Answer 1

I was setting the attributes in the wrong way. This is the correct way: g.node[1]["foo"] = "fighter"
