Solve the following python programming problem given the following code:
def categorical_node_match(attr, default) : 
    if nx.utils.is_string_like (attr) : 
        def match(data1, data2) : 
            return (data1.get (attr, default) == data2.get (attr, default)) 
else : 
        attrs = list (zip (match, default)) 
        def match(data1, data2) : 
            values1 = set ([data1.get (attr, d) for (attr, d) in attrs]) 
            values2 = set ([data2.get (attr, d) for (attr, d) in attrs]) 
            return (values1 == values2) 
return match 

    
    

    Fix the buggy line: attrs = list (zip (match, default))

#Here is Python program to fix the buggy line: attrs = list (zip (match, default))
.

attrs = list (zip (attr, default))
