[英]How to add edges in an igraph object from a dictionary
I'm using a dictionary to represent a set of edges. 我正在使用字典来表示一组边。 I'm using the keys of the dictionary to represent edges and the values to represent the weights.
我正在使用字典的键来表示边缘,并使用值来表示权重。 The dictionary currently looks like this:
字典目前看起来像这样:
{(0, 1): 2, (1, 2): 6, (0, 2): 3}
I try this: 我试试这个:
edges, weights = [], []
for edge, weight in dict_edges.items():
edges += [edge]
weights.append(weight)
g.add_edges(edges)
g.es["weight"] = weights
But, I don't if there is a faster way or more cleaner to do this. 但是,如果有更快的方式或更清洁,我不会这样做。
Anyone have any suggestions how to improve my new? 任何人有任何建议如何改善我的新?
What you do is perfectly fine; 你做的很完美; maybe the
for
loop could be replaced with a zip
call. 也许
for
循环可以用zip
调用替换。 If you are using Python 2.x:: 如果您使用的是Python 2.x ::
from itertools import izip
edges, weights = izip(*dict_edges.iteritems())
g = Graph(edges, edge_attrs={"weight": weights})
If you are using Python 3.x:: 如果您使用的是Python 3.x ::
edges, weights = zip(*dict_edges.items())
g = Graph(edges, edge_attrs={"weight": weights})
