Without seeing an example of what your list is, and what you want to turn it
into, its sort of hard to be certain what it is you really want to do.

Is it:

>>> a = range(100)
>>> a[2:-2] = [str(x) for x in a[2:-2]]
>>> a
[0, 1, '2', '3', '4', '5', '6', '7', '8', '9', '10', '11', '12', '13', '14',
'15', '16', '17', '18', '19', '20', '21', '22', '23', '24', '25', '26',
'27', '28', '29', '30', '31', '32', '33', '34', '35', '36', '37', '38',
'39', '40', '41', '42', '43', '44', '45', '46', '47', '48', '49', '50',
'51', '52', '53', '54', '55', '56', '57', '58', '59', '60', '61', '62',
'63', '64', '65', '66', '67', '68', '69', '70', '71', '72', '73', '74',
'75', '76', '77', '78', '79', '80', '81', '82', '83', '84', '85', '86',
'87', '88', '89', '90', '91', '92', '93', '94', '95', '96', '97', 98, 99]

Where I converted to a string the "inner" elements with a list comprehension
but left the outer ones alone?
