The rest of this conversation is just silly. It's turning into getting
hit on the head lessons.
I agree. In early Python, tuples were more different from lists than
they are today. They did not have any (public) methods. Today, they have
.index and .count methods, which make little sense from the 'tuple is a
record' viewpoint. The addition of those methods redefined tuples as
read-only (and therefore hashable) sequences.
From the collections.abc doc
'''
Sequence | Sized, Iterable, Container |
__getitem__ __contains__, __iter__, __reversed__, index, and count
...
class collections.abc.Sequence
class collections.abc.MutableSequence
ABCs for read-only and mutable sequences.

>>> from collections.abc import Sequence
>>> issubclass(tuple, Sequence)
