Create a new attribute on a class.
.. warning::
Does *not* do anything unless the class is also decorated with
:func:`attr.s`!
:param default: A value that is used if an ``attrs``-generated ``__init__``
is used and no value is passed while instantiating or the attribute is
excluded using ``init=False``.
If the value is an instance of :class:`Factory`, its callable will be
used to construct a new value (useful for mutable data types like lists
or dicts).
If a default is not set (or set manually to ``attr.NOTHING``), a value
*must* be supplied when instantiating; otherwise a :exc:`TypeError`
will be raised.
The default can also be set using decorator notation as shown below.
:type default: Any value.
:param callable factory: Syntactic sugar for
``default=attr.Factory(callable)``.
:param validator: :func:`callable` that is called by ``attrs``-generated
``__init__`` methods after the instance has been initialized. They
receive the initialized instance, the :class:`Attribute`, and the
passed value.
The return value is *not* inspected so the validator has to throw an
exception itself.
If a ``list`` is passed, its items are treated as validators and must
all pass.
Validators can be globally disabled and re-enabled using
:func:`get_run_validators`.
The validator can also be set using decorator notation as shown below.
:type validator: ``callable`` or a ``list`` of ``callable``\ s.
:param bool repr: Include this attribute in the generated ``__repr__``
method.
:param bool cmp: Include this attribute in the generated comparison methods
(``__eq__`` et al).
:param hash: Include this attribute in the generated ``__hash__``
method. If ``None`` (default), mirror *cmp*'s value. This is the
correct behavior according the Python spec. Setting this value to
anything else than ``None`` is *discouraged*.
:type hash: ``bool`` or ``None``
:param bool init: Include this attribute in the generated ``__init__``
method. It is possible to set this to ``False`` and set a default
value. In that case this attributed is unconditionally initialized
with the specified default value or factory.
:param callable converter: :func:`callable` that is called by
``attrs``-generated ``__init__`` methods to converter attribute's value
to the desired format. It is given the passed-in value, and the
returned value will be used as the new value of the attribute. The
value is converted before being passed to the validator, if any.
:param metadata: An arbitrary mapping, to be used by third-party
components. See :ref:`extending_metadata`.
:param type: The type of the attribute. In Python 3.6 or greater, the
preferred method to specify the type is using a variable annotation
(see `PEP 526 `_).
This argument is provided for backward compatibility.
Regardless of the approach used, the type will be stored on
``Attribute.type``.
Please note that ``attrs`` doesn't do anything with this metadata by
itself. You can use it as part of your own code or for
:doc:`static type checking `.
:param kw_only: Make this attribute keyword-only (Python 3+)
in the generated ``__init__`` (if ``init`` is ``False``, this
parameter is ignored).

A class decorator that adds `dunder
`_\ -methods according to the
specified attributes using :func:`attr.ib` or the *these* argument.
:param these: A dictionary of name to :func:`attr.ib` mappings. This is
useful to avoid the definition of your attributes within the class body
because you can't (e.g. if you want to add ``__repr__`` methods to
Django models) or don't want to.
If *these* is not ``None``, ``attrs`` will *not* search the class body
for attributes and will *not* remove any attributes from it.
If *these* is an ordered dict (:class:`dict` on Python 3.6+,
:class:`collections.OrderedDict` otherwise), the order is deduced from
the order of the attributes inside *these*. Otherwise the order
of the definition of the attributes is used.
:type these: :class:`dict` of :class:`str` to :func:`attr.ib`
:param str repr_ns: When using nested classes, there's no way in Python 2
to automatically detect that. Therefore it's possible to set the
namespace explicitly for a more meaningful ``repr`` output.
:param bool repr: Create a ``__repr__`` method with a human readable
representation of ``attrs`` attributes..
:param bool str: Create a ``__str__`` method that is identical to
``__repr__``. This is usually not necessary except for
:class:`Exception`\ s.
:param bool cmp: Create ``__eq__``, ``__ne__``, ``__lt__``, ``__le__``,
``__gt__``, and ``__ge__`` methods that compare the class as if it were
a tuple of its ``attrs`` attributes. But the attributes are *only*
compared, if the types of both classes are *identical*!
:param hash: If ``None`` (default), the ``__hash__`` method is generated
according how *cmp* and *frozen* are set.
1. If *both* are True, ``attrs`` will generate a ``__hash__`` for you.
2. If *cmp* is True and *frozen* is False, ``__hash__`` will be set to
None, marking it unhashable (which it is).
3. If *cmp* is False, ``__hash__`` will be left untouched meaning the
``__hash__`` method of the base class will be used (if base class is
``object``, this means it will fall back to id-based hashing.).
Although not recommended, you can decide for yourself and force
``attrs`` to create one (e.g. if the class is immutable even though you
didn't freeze it programmatically) by passing ``True`` or not. Both of
these cases are rather special and should be used carefully.
See the `Python documentation \
`_
and the `GitHub issue that led to the default behavior \
`_ for more details.
:type hash: ``bool`` or ``None``
:param bool init: Create a ``__init__`` method that initializes the
``attrs`` attributes. Leading underscores are stripped for the
argument name. If a ``__attrs_post_init__`` method exists on the
class, it will be called after the class is fully initialized.
:param bool slots: Create a slots_-style class that's more
memory-efficient. See :ref:`slots` for further ramifications.
:param bool frozen: Make instances immutable after initialization. If
someone attempts to modify a frozen instance,
:exc:`attr.exceptions.FrozenInstanceError` is raised.
Please note:
1. This is achieved by installing a custom ``__setattr__`` method
on your class so you can't implement an own one.
2. True immutability is impossible in Python.
3. This *does* have a minor a runtime performance :ref:`impact
` when initializing new instances. In other words:
``__init__`` is slightly slower with ``frozen=True``.
4. If a class is frozen, you cannot modify ``self`` in
``__attrs_post_init__`` or a self-written ``__init__``. You can
circumvent that limitation by using
``object.__setattr__(self, "attribute_name", value)``.
.. _slots: https://docs.python.org/3/reference/datamodel.html#slots
:param bool weakref_slot: Make instances weak-referenceable. This has no
effect unless ``slots`` is also enabled.
:param bool auto_attribs: If True, collect `PEP 526`_-annotated attributes
(Python 3.6 and later only) from the class body.
In this case, you **must** annotate every field. If ``attrs``
encounters a field that is set to an :func:`attr.ib` but lacks a type
annotation, an :exc:`attr.exceptions.UnannotatedAttributeError` is
raised. Use ``field_name: typing.Any = attr.ib(...)`` if you don't
want to set a type.
If you assign a value to those attributes (e.g. ``x: int = 42``), that
value becomes the default value like if it were passed using
``attr.ib(default=42)``. Passing an instance of :class:`Factory` also
works as expected.
Attributes annotated as :data:`typing.ClassVar` are **ignored**.
.. _`PEP 526`: https://www.python.org/dev/peps/pep-0526/
:param bool kw_only: Make all attributes keyword-only (Python 3+)
in the generated ``__init__`` (if ``init`` is ``False``, this
parameter is ignored).
:param bool cache_hash: Ensure that the object's hash code is computed
only once and stored on the object. If this is set to ``True``,
hashing must be either explicitly or implicitly enabled for this
class. If the hash code is cached, then no attributes of this
class which participate in hash code computation may be mutated
after object creation.
