Removing a particular index from a list

[Srikanth]

Hi,

list.remove(item) removes the first item from the list, but how do I
say to remove a particular index from a list without using it's value?

Let's say I have 4 items in my list as

>>> li = ["sri", "s", "srikanth", "s"]

And if I want to remove the last item ("s"), how do I remove it?
li.remove(-1) doesn't do it. This is my problem.

Thanks,
Srikanth
