- Graph.adjacency_iter()¶
Return an iterator of (node, adjacency dict) tuples for all nodes.
This is the fastest way to look at every edge. For directed graphs, only outgoing adjacencies are included.
Returns : adj_iter : iterator
An iterator of (node, adjacency dictionary) for all nodes in the graph.
