How can I count from the back in python lists

0 votes
Say I have a list
l = ['P','y','t','h','o','n']

I want to be able to use the last two items, but I'm not sure how long the list is because it was user-generated.

Therefore, it is impossible to do l[3:] because what if the list has seven (or any other number) entries instead of five?

How do I count backward from the list's back?
