Bug report

Bug description:

().index(0)# outputs "tuple.index(x): x not in tuple"[].index(0)# outputs "0 is not in list"

i think it'd be useful to normalize them to have the same value error, in tuple you can see that the item's value or name isn't even mentioned, unlike in list that the item's value is mentioned, although the name is not.

CPython versions tested on:

3.11

Operating systems tested on:
