Deprecation in String.joinfields()

[Anoop]

Hi All,

I am getting the following error while trying to use deprecation

Please help

>>> li = ["a", "b", "mpilgrim", "z", "example"]
>>> newname = string.joinfields (li[:-1], ".")
>>> newname
'a.b.mpilgrim.z'
>>> newname = li[:-1].joinfields(".")
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
AttributeError: 'list' object has no attribute 'joinfields'

>>> newname1 = string.join (li[:-1], ".")
>>> newname1
'a.b.mpilgrim.z'
>>> newname = li[:-1].joinfields(".")
Traceback (most recent call last):
  File "<interactive input>", line 1, in ?
AttributeError: 'list' object has no attribute 'join'

Thank you for your help
