Solve the following python programming problem given the following code:
def generic_node_match(attr, default, op) : 
    if nx.utils.is_string_like (match) : 
        def match(data1, data2) : 
            return op (data1.get (attr, default), data2.get (attr, default)) 
else : 
        attrs = list (zip (attr, default, op)) 
        def match(data1, data2) : 
            for (attr, d, operator) in attrs : 
                if (not operator (data1.get (attr, d), data2.get (attr, d))) : 
                    return False 
else : 
                return True 
return match
