random_triad

random_triad(G, seed=None)

Returns a random triad from a directed graph.

Deprecated since version 3.3: random_triad is deprecated and will be removed in version 3.5. Use random sampling directly instead:

G.subgraph(random.sample(list(G), 3))

Parameters:

Gdigraph

A NetworkX DiGraph

seedinteger, random_state, or None (default)

Indicator of random number generation state. See Randomness.

Returns:

G2subgraph

A randomly selected triad (order-3 NetworkX DiGraph)

Raises:

NetworkXError

If the input Graph has less than 3 nodes.

Examples

>>> G = nx.DiGraph([(1, 2), (1, 3), (2, 3), (3, 1), (5, 6), (5, 4), (6, 7)])
>>> triad = nx.random_triad(G, seed=1)
>>> triad.edges
OutEdgeView([(1, 2)])
