Solve the following python programming problem given the following code:
@ classmethod 
def _subclass_from_prefix(class_, prefix) : 
    'Get a column subclass for the given `prefix`.' 
    cname = ('%sCol' % prefix) 
    class_from_prefix = class_._class_from_prefix 
    if (cname in class_from_prefix) : 
        return class_from_prefix [cname] 
atombase = getattr (atom, ('%sAtom' % prefix)) 
    class NewCol (class_, atombase) : 
        'Defines a non-nested column of a particular type.

            The constructor accepts the same arguments as the equivalent
            `Atom` class, plus an additional ``pos`` argument for
            position information, which is assigned to the `_v_pos`
            attribute.

            ' 
        def __init__(self, * args, **kwargs) : 
            pos = kwargs.pop ('pos', None) 
            class_from_prefix = self._class_from_prefix 
            atombase.__init__ (self, * args, ** kwargs) 
            if (self.__class__ is not NewCol) : 
                colclass = class_from_prefix [self.prefix ()] 
                self.__class__ = colclass 
self._v_pos = pos 
__eq__ = same_position (atombase.__eq__) 
        _is_equal_to_atom = same_position (atombase._is_equal_to_atom) 
        if (prefix == 'Enum') : 
            _is_equal_to_enumatom = same_position (atombase._is_equal_to_enumatom) 
NewCol.__name__ = prefix 
    class_from_prefix [prefix] = NewCol 
    return NewCol 

    
    

    Fix the buggy line: NewCol.__name__ = prefix
assistant
#Here is Python code to fix the buggy line: NewCol.

NewCol.__name__ = cname
