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

>>> li = ["sri", "s", "srikanth", "s"]
>>> del li[-1]
>>> li ['sri', 's', 'srikanth']
>>>

li.pop() will remove the last element

del li[-1]

This is my problem.

I read this 2 months ago and I expected it to be a method of list, but
I sound like I am making an excuse. Thanks a lot.

No, that's OUR problem

And the fact that it's our /self-inflicted/ problem makes it all the more
severe
