Sorry, I thought it would be easier to ask this way. Guess not.

I am actually looking for a way to get a result from split which is
sliced the way I want. Like in my example above.
I mean I can probably make more variable by creating a tuple, but why?
What is the purpose if I want only couple elements out of split.
Doing it Perl way does not help:

C:\Documents and Settings\Igor.FORDANWORK\Desktop\winpdb>python
Python 2.7.5 (default, May 15 2013, 22:43:36) [MSC v.1500 32 bit
(Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> test = "I,like,my,chocolate"
>>> print test.split(',')[2,3]
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: list indices must be integers, not tuple

I can do it this way:

>>> testlist = test.split(',')
>>> print testlist[2]
my

but it will needlessly creates a list on which I will access by the index.

Why? All I need is couple of values out of n-dimensional list (array).

Well is there a Python way to do what I want?
I mention Perl only because I'm familiar with the language and this is
easy in it to do that.

Thank you.
