[New-bugs-announce] [issue21989] Missing (optional) argument `start` and `end` in documentation for list.index

[SylvainDe]

New submission from SylvainDe:

>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.
