http is a network protocol.
What does that have to do with traversing python lists?
Can you clarify what you mean by that?

Not with a standard list although its not hard to do by defining
your own class wrappibng a list.
You can however traverse a list using a standard for loop:
for item in [1,2,3,4,5]:
print item
And you can use range() to generate a set of indices
that will allow you to iterate by more unusual step sizes
And you can use normal indexing to go to the first element(0)
or the last element(-1)
I'm not sure if that answers your question.
