networkx.DiGraph.add_edges_from

DiGraph.add_edges_from(ebunch, data=1)

Add all the edges in ebunch.

Parameters:

ebunch : list or container of edges

The container must be iterable or an iterator. It is iterated over once. Adding the same edge twice has no effect and does not raise an exception. The edges in ebunch must be 2-tuples (u,v) or 3-tuples (u,v,d).

data : any Python object The default data for edges with no data given. If unspecified the integer 1 will be used.

Examples

>>> G=nx.DiGraph()
>>> G.add_edges_from([(0,1),(1,2)]) # using a list of edge tuples
>>> e=zip(range(0,3),range(1,4))
>>> G.add_edges_from(e) # Add the path graph 0-1-2-3
