From :

https://docs.python.org/2/tutorial/datastructures.html and
https://docs.python.org/3.4/tutorial/datastructures.html (and all other versions) :

----------------------------

    list.index(x)

    Return the index in the list of the first item whose value is x. It is an error if there is no such item.

----------------------------

From help(list) :

----------------------------
| index(...)
| L.index(value, [start, [stop]]) -> integer -- return first index of value.
| Raises ValueError if the value is not present.
----------------------------

Thus, second and third parameter are undocumented.

It's a tutorial, not API documentation. You will note that the 'key' and 'reverse' arguments to sort are not mentioned either.
