causal_networkx.graphs.dag.DAG.parents

DAG.parents(n)

Return an iterator over parents of node n.

Parents of node ‘n’ are nodes with a directed edge from ‘n’ to that node. For example, ‘n’ <- ‘x’, ‘n’ <- ‘y’. Nodes only connected via a bidirected edge are not considered parents: ‘n’ <-> ‘y’.

Parameters:

n : node

A node in the causal DAG.

Returns:

parents : Iterator

An iterator of the parents of node ‘n’.
