Solve the following python programming problem given the following code:
def __init__(self, * args, **kwargs) : 
    super (Filter, self).__init__ (* args, ** kwargs) 
    self._filters = [] 
    def _get_targets(spec_str) : 
        spec_parser = CmdLineSpecParser (get_buildroot ()) 
        try : 
            spec = spec_parser.parse_spec (spec_str) 
            addresses = self.context.address_mapper.scan_specs ([spec]) 
except AddressLookupError as e : 
            raise TaskError ('Failed to parse address selector: {spec_str}
 {message}'.format (spec_str = spec_str, message = e)) 
matches = set () 
        for address in addresses : 
            self.context.build_graph.inject_address_closure (address) 
            matches.add (self.context.build_graph.get_target (address)) 
if (not matches) : 
            raise TaskError ('No matches for address selector: {spec_str}'.format (spec_str = spec_str)) 
return matches 
def filter_for_address(spec) : 
        matches = _get_targets (spec) 
        return (lambda target : (target in matches)) 
self._filters.extend (create_filters (self.get_options ().target, filter_for_address)) 
    def filter_for_type(name) : 
        target_types = self.target_types_for_alias (name) 
        return (lambda target : isinstance (target, tuple (target_types))) 
self._filters.extend (create_filters (self.get_options ().type, filter_for_ancestor)) 
    def filter_for_ancestor(spec) : 
        ancestors = _get_targets (spec) 
        children = set () 
        for ancestor in ancestors : 
            ancestor.walk (children.add) 
return (lambda target : (target in children)) 
self._filters.extend (create_filters (self.get_options ().ancestor, filter_for_ancestor)) 
    def filter_for_regex(regex) : 
        try : 
            parser = re.compile (regex) 
except re.error as e : 
            raise TaskError ('Invalid regular expression: {}: {}'.format (regex, e)) 
return (lambda target : parser.search (str (target.address.spec))) 
self._filters.extend (create_filters (self.get_options ().regex, filter_for_regex)) 
    def filter_for_tag_regex(tag_regex)...

    
    

    Fix the buggy line: self._filters.extend (create_filters (self.get_options ().type, filter_for_ancestor))

#Here is Python code to fix the buggy line: self.

self._filters.extend (create_filters (self.get_options ().type, def filter_for_type())
