`field()` calls, or the *these* argument.

Since *attrs* patches or replaces an existing class, you cannot use

Args:

slots (bool):
|

Create a :term:`slotted class <slotted classes>` that's more

memory-efficient. Slotted classes are generally superior to the

default dict classes, but have some gotchas you should know about,

so we encourage you to read the :term:`glossary entry <slotted

*current* class (meaning, it is *not* inherited from some base
|
||||
class).
|
||||
|
||||
So, for example by implementing ``__eq__`` on a class yourself,
|
||||
*attrs* will deduce ``eq=False`` and will create *neither*
|
||||
``__eq__`` *nor* ``__ne__`` (but Python classes come with a
|
||||
sensible ``__ne__`` by default, so it *should* be enough to only
|
||||
implement ``__eq__`` in most cases).
|
||||

||||
Passing True or False` to *init*, *repr*, *eq*, or *hash*
|

overrides whatever *auto_detect* would determine.

any subclass of any exception), the following happens to behave
|
||||
like a well-behaved Python exception class:
|
||||
|
||||
- the values for *eq*, *order*, and *hash* are ignored and the
|
||||
instances compare and hash by the instance's ids [#]_ ,
|
||||
- all attributes that are either passed into ``__init__`` or have a
|
||||
default value are additionally available as a tuple in the
|
||||
``args`` attribute,
|
||||
- the value of *str* is ignored leaving ``__str__`` to base
|
||||
classes.
|
||||
|
||||
.. [#]
|
||||
Note that *attrs* will *not* remove existing implementations of
|
||||
``__hash__`` or the equality methods. It just won't add own
|
||||
ones.
|
||||
|
||||
on_setattr (~typing.Callable | list[~typing.Callable] | None | ~typing.Literal[attrs.setters.NO_OP]):
|
||||
A callable that is run whenever the user attempts to set an
|
||||
attribute (either by assignment like ``i.x = 42`` or by using
|
||||
`setattr` like ``setattr(i, "x", 42)``). It receives the same
|
||||
arguments as validators: the instance, the attribute that is being
|
||||
modified, and the new value.
|
||||
|
||||
If no exception is raised, the attribute is set to the return value
|
||||
of the callable.
|
||||
|
||||
If a list of callables is passed, they're automatically wrapped in
|
||||
an `attrs.setters.pipe`.
|
||||
|
||||
If left None, the default behavior is to run converters and
|
||||
validators whenever an attribute is set.
|
||||
|
||||
init (bool):
|
||||
Create a ``__init__`` method that initializes the *attrs*
|
||||
attributes. Leading underscores are stripped for the argument name,
|
||||
unless an alias is set on the attribute.
|
||||
|
||||
.. seealso::
|
||||
`init` shows advanced ways to customize the generated
|
||||
``__init__`` method, including executing code before and after.
|
||||
|
||||
repr(bool):
|
||||
Create a ``__repr__`` method with a human readable representation
|
||||
of *attrs* attributes.
|
||||
|
||||
str (bool):
|
||||
Create a ``__str__`` method that is identical to ``__repr__``. This
|
||||
is usually not necessary except for `Exception`\ s.
|
||||
|
||||
eq (bool | None):
|
||||
If True or None (default), add ``__eq__`` and ``__ne__`` methods
|
||||
that check two instances for equality.
|
||||
|
||||
.. seealso::
|
||||
`comparison` describes how to customize the comparison behavior
|
||||
going as far comparing NumPy arrays.
|
||||
|
||||
order (bool | None):
|
||||
If True, add ``__lt__``, ``__le__``, ``__gt__``, and ``__ge__``
|
||||
methods that behave like *eq* above and allow instances to be
|
||||
ordered.
|
||||
|
||||
They compare the instances as if they were tuples of their *attrs*
|
||||
attributes if and only if the types of both classes are
|
||||
*identical*.
|
||||
|
||||
If `None` mirror value of *eq*.
|
||||
|
||||
.. seealso:: `comparison`
|
||||
|
||||
unsafe_hash (bool | None):
|
||||
If None (default), the ``__hash__`` method is generated according
|
||||
how *eq* and *frozen* are set.
|
||||
|
||||
1. If *both* are True, *attrs* will generate a ``__hash__`` for
|
||||
you.
|
||||
2. If *eq* is True and *frozen* is False, ``__hash__`` will be set
|
||||
to None, marking it unhashable (which it is).
|
||||
3. If *eq* is False, ``__hash__`` will be left untouched meaning
|
||||
the ``__hash__`` method of the base class will be used. If the
|
||||
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 (for example, 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.

||||

||||

|
||||
<https://github.com/python-attrs/attrs/issues/136>`_ for more
|
||||
details.
|
||||
|
||||
hash (bool | None):
|
||||
Deprecated alias for *unsafe_hash*. *unsafe_hash* takes precedence.
|
||||
|
||||
cache_hash (bool):
|
||||
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, avoid any reassignments of fields involved in hash code
|
||||
computation or mutations of the objects those fields point to after
|
||||
object creation. If such changes occur, the behavior of the
|
||||
object's hash code is undefined.
|
||||
|
||||
frozen (bool):
|
||||
Make instances immutable after initialization. If someone attempts
|
||||
to modify a frozen instance, `attrs.exceptions.FrozenInstanceError`
|
||||
is raised.
|
||||
|
||||
.. note::
|
||||
|
||||
1. This is achieved by installing a custom ``__setattr__``
|
||||
method on your class, so you can't implement your own.
|
||||
|
||||
2. True immutability is impossible in Python.
|
||||
|
||||
3. This *does* have a minor a runtime performance `impact
|
||||
<how-frozen>` 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)``.
|
||||
|
||||
5. Subclasses of a frozen class are frozen too.
|
||||
|
||||
kw_only (bool):
|
||||
Make all attributes keyword-only in the generated ``__init__`` (if
|
||||
*init* is False, this parameter is ignored).
|
||||
|
||||
weakref_slot (bool):
|
||||
Make instances weak-referenceable. This has no effect unless
|
||||
*slots* is True.
|
||||
|
||||
field_transformer (~typing.Callable | None):
|
||||
A function that is called with the original class object and all
|
||||
fields right before *attrs* finalizes the class. You can use this,
|
||||
for example, to automatically add converters or validators to
|
||||
fields based on their types.
|
||||
|
||||
.. seealso:: `transform-fields`
|
||||
|
||||
match_args (bool):
|
||||
If True (default), set ``__match_args__`` on the class to support
|
||||
:pep:`634` (*Structural Pattern Matching*). It is a tuple of all
|
||||
non-keyword-only ``__init__`` parameter names on Python 3.10 and
|
||||
later. Ignored on older Python versions.
|
||||
|
||||
collect_by_mro (bool):
|
||||
If True, *attrs* collects attributes from base classes correctly
|
||||
according to the `method resolution order
|
||||
<https://docs.python.org/3/howto/mro.html>`_. If False, *attrs*
|
||||
will mimic the (wrong) behavior of `dataclasses` and :pep:`681`.
|
||||
|
||||
See also `issue #428
|
||||
<https://github.com/python-attrs/attrs/issues/428>`_.
|
||||
|
||||
getstate_setstate (bool | None):
|
||||
.. note::
|
||||
|
||||
This is usually only interesting for slotted classes and you
|
||||
should probably just set *auto_detect* to True.
|
||||
|
||||
If True, ``__getstate__`` and ``__setstate__`` are generated and
|
||||
attached to the class. This is necessary for slotted classes to be
|
||||
pickleable. If left None, it's True by default for slotted classes
|
||||
and False for dict classes.
|
||||
|
||||
If *auto_detect* is True, and *getstate_setstate* is left None, and
|
||||
**either** ``__getstate__`` or ``__setstate__`` is detected
|
||||
directly on the class (meaning: not inherited), it is set to False
|
||||
(this is usually what you want).
|
||||
|
||||
auto_attribs (bool | None):
|
||||
If True, look at type annotations to determine which attributes to
|
||||
use, like `dataclasses`. If False, it will only look for explicit
|
||||
:func:`field` class attributes, like classic *attrs*.
|
||||
|
||||
If left None, it will guess:
|
||||
|
||||
1. If any attributes are annotated and no unannotated
|
||||
`attrs.field`\ s are found, it assumes *auto_attribs=True*.
|
||||
2. Otherwise it assumes *auto_attribs=False* and tries to collect
|
||||
`attrs.field`\ s.
|
||||
|
||||
If *attrs* decides to look at type annotations, **all** fields
|
||||
**must** be annotated. If *attrs* encounters a field that is set to
|
||||
a :func:`field` / `attr.ib` but lacks a type annotation, an
|
||||
`attrs.exceptions.UnannotatedAttributeError` is raised. Use
|
||||
``field_name: typing.Any = field(...)`` if you don't want to set a
|
||||
type.
|
||||
|
||||
.. warning::
|
||||
|
||||
For features that use the attribute name to create decorators
|
||||
(for example, :ref:`validators <validators>`), you still *must*
|
||||
assign :func:`field` / `attr.ib` to them. Otherwise Python will
|
||||
either not find the name or try to use the default value to
|
||||
call, for example, ``validator`` on it.
|
||||
|
||||
Attributes annotated as `typing.ClassVar`, and attributes that are
|
||||
neither annotated nor set to an `field()` are **ignored**.
|
||||
|
||||
these (dict[str, object]):
|
||||
A dictionary of name to the (private) return value of `field()`
|
||||
mappings. This is useful to avoid the definition of your attributes
|
||||
within the class body because you can't (for example, 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.
|
||||
|
||||
The order is deduced from the order of the attributes inside
|
||||
*these*.
|
||||
|
||||
Arguably, this is a rather obscure feature.
|
||||
|
||||
.. versionadded:: 20.1.0
|
||||
.. versionchanged:: 21.3.0 Converters are also run ``on_setattr``.
|
||||
.. versionadded:: 22.2.0
|
||||
*unsafe_hash* as an alias for *hash* (for :pep:`681` compliance).
|
||||
.. versionchanged:: 24.1.0
|
||||
Instances are not compared as tuples of attributes anymore, but using a
|
||||
big ``and`` condition. This is faster and has more correct behavior for
|
||||
uncomparable values like `math.nan`.
|
||||
.. versionadded:: 24.1.0
|
||||
If a class has an *inherited* classmethod called
|
||||
``__attrs_init_subclass__``, it is executed after the class is created.
|
||||
.. deprecated:: 24.1.0 *hash* is deprecated in favor of *unsafe_hash*.
|
||||
.. versionadded:: 24.3.0
|
||||
Unless already present, a ``__replace__`` method is automatically
|
||||
created for `copy.replace` (Python 3.13+ only).
|
||||
|
||||
.. note::
|
||||
|
||||
The main differences to the classic `attr.s` are:
|
||||
|
||||
- Automatically detect whether or not *auto_attribs* should be `True`
|
||||
(c.f. *auto_attribs* parameter).
|
||||
- Converters and validators run when attributes are set by default --
|
||||
if *frozen* is `False`.
|
||||
- *slots=True*
|
||||
|
||||
Usually, this has only upsides and few visible effects in everyday
|
||||
programming. But it *can* lead to some surprising behaviors, so
|
||||
please make sure to read :term:`slotted classes`.
|
||||
|
||||
- *auto_exc=True*
|
||||
- *auto_detect=True*
|
||||
- *order=False*
|
||||
- Some options that were only relevant on Python 2 or were kept around
|
||||
for backwards-compatibility have been removed.

*attrs* is the Python package that will bring back the **joy** of **writing classes** by relieving you from the drudgery of implementing object protocols (aka [dunder methods](https://www.attrs.org/en/latest/glossary.html#term-dunder-methods)).
|
||||
[Trusted by NASA](https://docs.github.com/en/account-and-profile/setting-up-and-managing-your-github-profile/customizing-your-profile/personalizing-your-profile#list-of-qualifying-repositories-for-mars-2020-helicopter-contributor-achievement) for Mars missions since 2020!
|
||||
|
||||
Its main goal is to help you to write **concise** and **correct** software without slowing down your code.
|
||||
|
||||
|
||||
## Sponsors

## Example
|
||||
|
||||
*attrs* gives you a class decorator and a way to declaratively define the attributes on that class:
|
||||
|
||||
<!-- code-begin -->
|
||||
|
||||
```pycon
|
||||
>>> from attrs import asdict, define, make_class, Factory
|
||||
|
||||
>>> @define
|
||||
... class SomeClass:
|
||||
... a_number: int = 42
|
||||
... list_of_numbers: list[int] = Factory(list)
|
||||
...
|
||||
... def hard_math(self, another_number):
|
||||
... return self.a_number + sum(self.list_of_numbers) * another_number
|
||||
|
||||
|
||||
>>> sc = SomeClass(1, [1, 2, 3])
|
||||

|

|

After *declaring* your attributes, *attrs* gives you:
|
||||
|
||||
- a concise and explicit overview of the class's attributes,
|
||||
- a nice human-readable `__repr__`,
|
||||
- equality-checking methods,
|
||||
- an initializer,
|
||||
- and much more,
|
||||
|
||||
*without* writing dull boilerplate code again and again and *without* runtime performance penalties.
|
||||
|
||||
---
|
||||
|
||||
This example uses *attrs*'s modern APIs that have been introduced in version 20.1.0, and the *attrs* package import name that has been added in version 21.3.0.
|
||||
The classic APIs (`@attr.s`, `attr.ib`, plus their serious-business aliases) and the `attr` package import name will remain **indefinitely**.
|
||||
|
||||
Check out [*On The Core API Names*](https://www.attrs.org/en/latest/names.html) for an in-depth explanation!
|
||||
|
||||
|
||||
### Hate Type Annotations!?
|
||||
|
||||
No problem!
|
||||
Types are entirely **optional** with *attrs*.
|
||||
Simply assign `attrs.field()` to the attributes instead of annotating them with types:
|
||||
|
||||
```python
|
||||
from attrs import define, field
|
||||
|
||||
@define
|
||||
class SomeClass:
|
||||
a_number = field(default=42)
|
||||
list_of_numbers = field(factory=list)
|
||||
```
|
||||
|
||||
|
||||
## Data Classes
|
||||
|
||||
On the tin, *attrs* might remind you of `dataclasses` (and indeed, `dataclasses` [are a descendant](https://hynek.me/articles/import-attrs/) of *attrs*).
|
||||
In practice it does a lot more and is more flexible.
|
||||
For instance, it allows you to define [special handling of NumPy arrays for equality checks](https://www.attrs.org/en/stable/comparison.html#customization), allows more ways to [plug into the initialization process](https://www.attrs.org/en/stable/init.html#hooking-yourself-into-initialization), has a replacement for `__init_subclass__`, and allows for stepping through the generated methods using a debugger.
|
||||
|
||||
For more details, please refer to our [comparison page](https://www.attrs.org/en/stable/why.html#data-classes), but generally speaking, we are more likely to commit crimes against nature to make things work that one would expect to work, but that are quite complicated in practice.

## Release Information
|
||||
|
||||
### Backwards-incompatible Changes
|
||||
|
||||
- Python 3.7 has been dropped.
|
||||
[#1340](https://github.com/python-attrs/attrs/issues/1340)
|
||||
|
||||
|
||||
### Changes
|
||||
|
||||
- Introduce `attrs.NothingType`, for annotating types consistent with `attrs.NOTHING`.
|
||||
[#1358](https://github.com/python-attrs/attrs/issues/1358)
|
||||
- Allow mutating `__suppress_context__` and `__notes__` on frozen exceptions.
|
||||
[#1365](https://github.com/python-attrs/attrs/issues/1365)
|
||||
- `attrs.converters.optional()` works again when taking `attrs.converters.pipe()` or another Converter as its argument.
|
||||
[#1372](https://github.com/python-attrs/attrs/issues/1372)
|
||||
- *attrs* instances now support [`copy.replace()`](https://docs.python.org/3/library/copy.html#copy.replace).
|
||||
[#1383](https://github.com/python-attrs/attrs/issues/1383)
|
||||
- `attrs.validators.instance_of()`'s type hints now allow for union types.
|
||||
For example: `instance_of(str | int)`
|
||||

==========
|
||||
|
||||
Click is a Python package for creating beautiful command line interfaces
|
||||
in a composable way with as little code as necessary. It's the "Command
|
||||
Line Interface Creation Kit". It's highly configurable but comes with
|
||||
sensible defaults out of the box.
|
||||
|
||||
It aims to make the process of writing command line tools quick and fun
|
||||
while also preventing any frustration caused by the inability to
|
||||
implement an intended CLI API.
|
||||
|
||||
Click in three points:
|
||||
|
||||
- Arbitrary nesting of commands
|
||||
- Automatic help page generation
|
||||
- Supports lazy loading of subcommands at runtime
|
||||
|
||||
|
||||
