-
generic_edge_match
(attr, default, op)[source]¶ Returns a comparison function for a generic attribute.
The value(s) of the attr(s) are compared using the specified operators. If all the attributes are equal, then the constructed function returns True.
- Parameters
attr (string | list) – The edge attribute to compare, or a list of edge attributes to compare.
default (value | list) – The default value for the edge attribute, or a list of default values for the edge attributes.
op (callable | list) – The operator to use when comparing attribute values, or a list of operators to use when comparing values for each attribute.
- Returns
match – The customized, generic
edge_match
function.- Return type

Examples
>>> from operator import eq >>> from networkx.algorithms.isomorphism.matchhelpers import close >>> from networkx.algorithms.isomorphism import generic_edge_match >>> nm = generic_edge_match("weight", 1.0, close) >>> nm = generic_edge_match("color", "red", eq) >>> nm = generic_edge_match(["weight", "color"], [1.0, "red"], [close, eq])
