categorical_multiedge_match
(attr, default)[source]¶ Returns a comparison function for a categorical edge attribute.
The value(s) of the attr(s) must be hashable and comparable via the == operator since they are placed into a set([]) object. If the sets from G1 and G2 are the same, then the constructed function returns True.
Parameters: - attr (string | list) – The categorical edge attribute to compare, or a list of categorical edge attributes to compare.
- default (value | list) – The default value for the categorical edge attribute, or a list of default values for the categorical edge attributes.
Returns: match – The customized, categorical
edge_match

>>> import networkx.algorithms.isomorphism as iso >>> nm = iso.categorical_multiedge_match('size', 1) >>> nm = iso.categorical_multiedge_match(['color', 'size'], ['red', 2])
