Solve the following python programming problem given the following code:
def namedtuple(typename, field_names, verbose = False, rename = False) : 
    'A collections.namedtuple implementation written in Python
        to support Python versions < 2.6.

        Taken from: http://code.activestate.com/recipes/500261/
        ' 
    if isinstance (field_names, basestring) : 
        field_names = field_names.replace (',', ' ').split () 
field_names = tuple (map (str, field_names)) 
    if rename : 
        names = list (field_names) 
        seen = set () 
        for (i, name) in enumerate (names) : 
            if ((not min (((c.isalnum () or (c == '_')) for c in name))) or _iskeyword (name) or (not name) or name [0].isdigit () or name.startswith ('_') or (name in seen)) : 
                names [i] = ('_%d' % i) 
seen.add (name) 
field_names = tuple (names) 
for name in ((typename,) + field_names) : 
        if (not min (((c.isalnum () or (c == '_')) for c in name))) : 
            raise ValueError (('Type names and field names can only contain alphanumeric characters and underscores: %r' % name)) 
if _iskeyword (name) : 
            raise ValueError (('Type names and field names cannot be a keyword: %r' % name)) 
if name [0].isdigit () : 
            raise ValueError (('Type names and field names cannot start with a number: %r' % name)) 
seen_names = set () 
    for name in field_names : 
        if (name.startswith ('_') and (not rename)) : 
            raise ValueError (('Field names cannot start with an underscore: %r' % name)) 
if (name in seen_names) : 
            raise ValueError (('Encountered duplicate field name: %r' % name)) 
seen_names.add (name) 
numfields = len (field_names) 
    argtxt = repr (field_names).replace ("'", '') [1 : (- 1)] 
    reprtxt = ', '.join ((('%s=%%r' % name) for name in field_names)) 
    template = ("class %(typename)s(tuple):
        '%(typename)s(%(argtxt)s)' 

        __slots__ = () 

        _fields = %(field_names)r 

        def __new__(_cls, %(argtxt)s):
            return _tuple.__new__(_cls, (%(argtxt)s)) 

        @classmethod
    ...

    
    

    Fix the buggy line: template += ('        %s = _property(_itemgetter(%d))
' % (rename, i))
assistant
#Here is Python program to fix the buggy line: template += ('        %s = _property(_itemgetter(%d))

template += ('        %s = _property(_itemgetter(%d))
