categorical_node_match(attr, default)

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 node attribute to compare, or a list of categorical node attributes to compare.

default : value | list

The default value for the categorical node attribute, or a list of default values for the categorical node attributes.

Returns

match : function

The customized, categorical :None:None:`node_match` function.

Returns a comparison function for a categorical node attribute.

Examples

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

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
