Solve the following python programming problem given the following code:
def default_iget(fields, default = None) : 
    " itemgetter with 'default' handling, that *always* returns lists

    API CHANGES from ``operator.itemgetter``

    Note: Sorry to break the iget api... (fields vs *fields)
    Note: *always* returns a list... unlike itemgetter,
        which can return tuples or 'singles'
    " 
    myiget = operator.itemgetter (* fields) 
    L = len (fields) 
    def f(thing) : 
        try : 
            ans = list (myiget (thing)) 
            if (L < 2) : 
                ans = [ans] 
return ans 
except KeyError : 
            return [thing.get (x, default) for x in fields] 
f.__doc__ = ('itemgetter with default %r for fields %r' % (default, f)) 
    f.__name__ = 'default_itemgetter' 
    return f 

    
    

    Fix the buggy line: f.__doc__ = ('itemgetter with default %r for fields %r' % (default, f))

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

f.__doc__ = ('itemgetter with default %r for fields %r' % (default, fields))
