schen added the comment:
What is the rationale for the inconsistency between tuples and lists here?
().index(0)
ValueError: tuple.index(x): x not in tuple
[].index(0)
ValueError: 0 is not in list
In this simple artificial case, it seems clear to me that the list version
(which is similar to the proposed change) is superior.
However, it is often not sufficient to use such cases as the basis for making a
decision. Raymond raises some very good points.
In particular, I noticed that printing the repr quickly becomes unwieldy for
more complex objects. For example, I tried the following:
[].index(''.join(chr(randrange(97, 97+26)) for _ in range(1000)))
[].index(Counter(randrange(10) for _ in range(10000)))
