在python中更改igraph中的特定节点属性名称

Question

I have an attribute called name in a graph g . I would like to change the name of one specific node associated with the attribute to a different name.

For example I have

from igraph import *
g = Graph(4)
g.vs['name'] = [(10,1), (269,1331), (3,1), (10,10)]
print g.vs['name']
[(10,1), (269,1331), (3,1), (10,10)]

I would like (3,1) to know be called (4,10) , so the output should be

print g.vs['name']
[(10,1), (269,1331), (4,10), (10,10)]

Answer 1

First, find the index of the node that is currently called (3, 1) :

index = g.vs["name"].index((3, 1))

Then, change the name of the node with that index:

g.vs[index]["name"] = (4, 10)
