cfpq_data.graphs.utils.filter_edges

filter_edges(graph: MultiDiGraph, labels: Iterable[Any]) → MultiDiGraph

Returns a graph with filtered edges.

Parameters:

• graph (MultiDiGraph) -- Initial graph.

• labels (Iterable[Any]) -- Graph edge labels to be preserved.

Examples

>>> from cfpq_data import *
>>> g = labeled_two_cycles_graph(1, 1, labels=("a", "b"))
>>> list(g.edges(data=True))
[(1, 0, {'label': 'a'}), (0, 1, {'label': 'a'}), (0, 2, {'label': 'b'}), (2, 0, {'label': 'b'})]
>>> new_g = filter_edges(g, ["a"])
>>> list(new_g.edges(data=True))
[(1, 0, {'label': 'a'}), (0, 1, {'label': 'a'})]

Returns:

g -- Graph with filtered edges.

Return type:

MultiDiGraph
