2) Lists are :term:`mutable`, which means that you can change their content.

+After the call to :meth:`!append`, the content of the mutable object has
changed from ``[]`` to ``[10]``. Since both the variables refer to the same
object, using either name accesses the modified value ``[10]``.
:meth:`~object.__iadd__` magic method, it gets called when the ``+=`` augmented

and returning the list. That's why we say that for lists, ``+=`` is a
"shorthand" for :meth:`!list.extend`::
``float('NaN')`` that are not equal to themselves.
