out_edges¶

DiGraph.
out_edges
(nbunch=None, data=False)¶ Return a list of edges.
Edges are returned as tuples with optional data in the order (node, neighbor, data).
Parameters: nbunch : iterable container, optional (default= all nodes)
A container of nodes. The container will be iterated through once.
data : bool, optional (default=False)
Return two tuples (u,v) (False) or threetuples (u,v,data) (True).
Returns: edge_list: list of edge tuples
Edges that are adjacent to any node in nbunch, or a list of all edges if nbunch is not specified.
See also
edges_iter
 return an iterator over the edges
Notes
Nodes in nbunch that are not in the graph will be (quietly) ignored. For directed graphs this returns the outedges.
Examples
>>> G = nx.Graph() # or DiGraph, MultiGraph, MultiDiGraph, etc >>> G.add_path([0,1,2,3]) >>> G.edges() [(0, 1), (1, 2), (2, 3)] >>> G.edges(data=True) # default edge data is {} (empty dictionary) [(0, 1, {}), (1, 2, {}), (2, 3, {})] >>> G.edges([0,3]) [(0, 1), (3, 2)] >>> G.edges(0) [(0, 1)]
