示例1: to_undirected

# 或者: from networkx.classes.graph.Graph import node [as 别名]
def to_undirected(self):
"""Return an undirected representation of the digraph.
Returns
-------
G : Graph
An undirected graph with the same name and nodes and
with edge (u,v,data) if either (u,v,data) or (v,u,data)
is in the digraph. If both edges exist in digraph and
their edge data is different, only one edge is created
with an arbitrary choice of which edge data to use.
You must check and correct for this manually if desired.
Notes
-----
If edges in both directions (u,v) and (v,u) exist in the
graph, attributes for the new undirected edge will be a combination of
the attributes of the directed edges. The edge data is updated
in the (arbitrary) order that the edges are encountered. For
more customized control of the edge attributes use add_edge().
This is similar to Graph(self) which returns a shallow copy.
self.to_undirected() returns a deepcopy of edge, node and
graph attributes.

This returns a "deepcopy" of the edge, node, and

all of the data and references.
This is in contrast to the similar G=DiGraph(D) which returns a
shallow copy of the data.
See the Python copy module for more information on shallow
and deep copies, http://docs.python.org/library/copy.html.
Warning
-------
If you have subclassed DiGraph to use dict-like objects in the
data structure, those changes do not transfer to the Graph
created by this method.
