Python: Retrieve Items From List

Question

Hi everyone,
I'm struggling with solving the problem described in this thread:
http://forums.arcgis.com/threads/39912-looped-block-selections

I started a new thread because I have questions specifically related to lists in python.
Lets say my list is:
list = [2,4,6,8]
I want to be able to do 2 things which I thought should be fairly simple:
1. Get the total number of items in the list (4)
2. Get the value of a list item at a specific index (eg. return 6 for index value 3 - or 2 if the index starts at 0)

The methods listed here: http://docs.python.org/tutorial/datastructures.html don't seem to do either of those things.  Is there some alternate method or object that would allow me to do that?
Thanks!

Length of listlen(listing)

Get index starts at zero, so for your examplelisting = [2,4,6,8]

To get 6 you would dolisting[2]
