This object is commonly used used to indicate that something is
omitted. It supports no special operations. There is exactly one
ellipsis object, named "Ellipsis" (a built-in name).
"type(Ellipsis)()" produces the "Ellipsis" singleton.
It is written as "Ellipsis" or "...".
In typical use, "..." as the "Ellipsis" object appears in a few
different places, for instance:
* In type annotations, such as callable arguments or tuple elements.
* As the body of a function instead of a pass statement.
* In third-party libraries, such as Numpy’s slicing and striding.
Python also uses three dots in ways that are not "Ellipsis" objects,
for instance:
* Doctest’s "ELLIPSIS", as a pattern for missing content.
* The default Python prompt of the *interactive* shell when partial
input is incomplete.
Lastly, the Python documentation often uses three dots in conventional
English usage to mean omitted content, even in code examples that also
use them as the "Ellipsis".

"except*" clause
----------------
The "except*" clause(s) are used for handling "ExceptionGroup"s. The
exception type for matching is interpreted as in the case of "except",
but in the case of exception groups we can have partial matches when
the type matches some of the exceptions in the group. This means that
multiple "except*" clauses can execute, each handling part of the
exception group. Each clause executes at most once and handles an
exception group of all matching exceptions. Each exception in the
group is handled by at most one "except*" clause, the first that
matches it.
The "except*" clause(s) specify one or more handlers for groups of
exceptions ("BaseExceptionGroup" instances). A "try" statement can
have either "except" or "except*" clauses, but not both. The exception
type for matching is mandatory in the case of "except*", so "except*:"
is a syntax error. The type is interpreted as in the case of "except",
but matching is performed on the exceptions contained in the group
that is being handled. An "TypeError" is raised if a matching type is
a subclass of "BaseExceptionGroup", because that would have ambiguous
semantics.
When an exception group is raised in the try block, each "except*"
clause splits (see "split()") it into the subgroups of matching and
non-matching exceptions. If the matching subgroup is not empty, it
becomes the handled exception (the value returned from
"sys.exception()") and assigned to the target of the "except*" clause
(if there is one). Then, the body of the "except*" clause executes. If
the non-matching subgroup is not empty, it is processed by the next
"except*" in the same manner. This continues until all exceptions in
the group have been matched, or the last "except*" clause has run.
After all "except*" clauses execute, the group of unhandled exceptions
is merged with any exceptions that were raised or re-raised from
within "except*" clauses. This merged exception group propagates on.:

2. The optional argument *i* defaults to "-1", so that by default the
last item is removed and returned.
3. "remove()" raises "ValueError" when *x* is not found in *s*.

5. "clear()" and "copy()" are included for consistency with the
interfaces of mutable containers that don’t support slicing
operations (such as "dict" and "set"). "copy()" is not part of the
"collections.abc.MutableSequence" ABC, but most concrete mutable
sequence classes provide it.
Added in version 3.3: "clear()" and "copy()" methods.
6. The value *n* is an integer, or an object implementing
2. The value *n* is an integer, or an object implementing
"__index__()". Zero and negative values of *n* clear the sequence.
Items in the sequence are not copied; they are referenced multiple
times, as explained for "s * n" under Common Sequence Operations.
-[ Mutable Sequence Methods ]-
Mutable sequence types also support the following methods:
sequence.append(value, /)
Append *value* to the end of the sequence This is equivalent to
writing "seq[len(seq):len(seq)] = [value]".
sequence.clear()
Added in version 3.3.
Remove all items from *sequence*. This is equivalent to writing
"del sequence[:]".
sequence.copy()
Added in version 3.3.
Create a shallow copy of *sequence*. This is equivalent to writing
"sequence[:]".
Hint:
The "copy()" method is not part of the "MutableSequence" "ABC",
but most concrete mutable sequence types provide it.
sequence.extend(iterable, /)
Extend *sequence* with the contents of *iterable*. For the most
part, this is the same as writing "seq[len(seq):len(seq)] =
iterable".
sequence.insert(index, value, /)
Insert *value* into *sequence* at the given *index*. This is
equivalent to writing "sequence[index:index] = [value]".
sequence.pop(index=-1, /)
Retrieve the item at *index* and also removes it from *sequence*.
By default, the last item in *sequence* is removed and returned.
sequence.remove(value, /)
Remove the first item from *sequence* where "sequence[i] == value".
Raises "ValueError" if *value* is not found in *sequence*.
sequence.reverse()
Reverse the items of *sequence* in place. This method maintains
economy of space when reversing a large sequence. To remind users
that it operates by side-effect, it returns "None".

.. section: C API
Attempting to acquire the GIL after runtime finalization has begun in a
different thread now causes the thread to hang rather than terminate, which
avoids potential crashes or memory corruption caused by attempting to
terminate a thread that is running code not specifically designed to support
termination. In most cases this hanging is harmless since the process will
soon exit anyway.
While not officially marked deprecated until 3.14, ``PyThread_exit_thread``
is no longer called internally and remains solely for interface
compatibility. Its behavior is inconsistent across platforms, and it can
only be used safely in the unlikely case that every function in the entire
call stack has been designed to support the platform-dependent termination
mechanism. It is recommended that users of this function change their
design to not require thread termination. In the unlikely case that thread
termination is needed and can be done safely, users may migrate to calling
platform-specific APIs such as ``pthread_exit`` (POSIX) or ``_endthreadex``
(Windows) directly.

avoids potential crashes or memory corruption caused by attempting to
terminate a thread that is running code not specifically designed to support
termination. In most cases this hanging is harmless since the process will
soon exit anyway.
While not officially marked deprecated until 3.14, ``PyThread_exit_thread``
is no longer called internally and remains solely for interface compatibility.
Its behavior is inconsistent across platforms, and it can only be used safely
in the unlikely case that every function in the entire call stack has been
designed to support the platform-dependent termination mechanism. It is
recommended that users of this function change their design to not require
thread termination. In the unlikely case that thread termination is needed and
can be done safely, users may migrate to calling platform-specific APIs such as
``pthread_exit`` (POSIX) or ``_endthreadex`` (Windows) directly.
