Create a new attribute on a class.
Warning
Does not do anything unless the class is also decorated with attr.s / attrs.define / and so on!
Please consider using attrs.field in new code (
attr.ib
will never go away, though).- Parameters:
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 usinginit=False
.If the value is an instance of attrs.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 attrs.NOTHING), a value must be supplied when instantiating; otherwise a TypeError will be raised.
The default can also be set using decorator notation as shown below.
See also
defaults
factory (callable) – Syntactic sugar for
default=attr.Factory(factory)
.validator (callable or a list of callables.) –
callable that is called by attrs-generated
__init__
methods after the instance has been initialized. They receive the initialized instance, theAttribute()
, 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 attrs.validators.get_disabled / attrs.validators.set_disabled.
The validator can also be set using decorator notation as shown below.
See also
validators
repr (a bool or a callable to use a custom function.) – Include this attribute in the generated
__repr__
method. IfTrue
, include the attribute; ifFalse
, omit it. By default, the built-inrepr()
function is used. To override how the attribute value is formatted, pass acallable
that takes a single value and returns a string. Note that the resulting string is used as-is, i.e. it will be used directly instead of callingrepr()
(the default).eq (a bool or a callable.) –
If
True
(default), include this attribute in the generated__eq__
and__ne__
methods that check two instances for equality. To override how the attribute value is compared, pass acallable
that takes a single value and returns the value to be compared.See also
comparison
order (a bool or a callable.) –
If
True
(default), include this attributes in the generated__lt__
,__le__
,__gt__
and__ge__
methods. To override how the attribute value is ordered, pass acallable
that takes a single value and returns the value to be ordered.See also
comparison
cmp (a bool or a callable.) –
Setting cmp is equivalent to setting eq and order to the same value. Must not be mixed with eq or order.
See also
comparison
hash (bool | None) –
Include this attribute in the generated
__hash__
method. IfNone
(default), mirror eq’s value. This is the correct behavior according the Python spec. Setting this value to anything else thanNone
is discouraged.See also
hashing
init (bool) –
Include this attribute in the generated
__init__
method. It is possible to set this toFalse
and set a default value. In that case this attributed is unconditionally initialized with the specified default value or factory.See also
init
converter (callable) –
callable that is called by attrs-generated
__init__
methods to convert 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.See also
converters
metadata (dict | None) – An arbitrary mapping, to be used by third-party components. See extending-metadata.
type –
The type of the attribute. Nowadays, 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 static type checking <types>.
kw_only (bool) – Make this attribute keyword-only in the generated
__init__
(ifinit
isFalse
, this parameter is ignored).on_setattr (callable, or a list of callables, or None, or attrs.setters.NO_OP) – Allows to overwrite the on_setattr setting from attr.s. If left None, the on_setattr value from attr.s is used. Set to attrs.setters.NO_OP to run no setattr hooks for this attribute – regardless of the setting in attr.s.
alias (str | None) – Override this attribute’s parameter name in the generated
__init__
method. If left None, default toname
stripped of leading underscores. See private-attributes.

- datumaro.components.annotations.merger.attrs(maybe_cls=None, these=None, repr_ns=None, repr=None, cmp=None, hash=None, init=None, slots=False, frozen=False, weakref_slot=True, str=False, auto_attribs=False, kw_only=False, cache_hash=False, auto_exc=False, eq=None, order=None, auto_detect=False, collect_by_mro=False, getstate_setstate=None, on_setattr=None, field_transformer=None, match_args=True, unsafe_hash=None)[source]#
A class decorator that adds dunder methods according to the specified attributes using attr.ib or the these argument.
Please consider using attrs.define / attrs.frozen in new code (
attr.s
will never go away, though).- Parameters:
these (dict of str to attr.ib) –
A dictionary of name to 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.The order is deduced from the order of the attributes inside these.
repr_ns (str) – 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.auto_detect (bool) –
Instead of setting the init, repr, eq, order, and hash arguments explicitly, assume they are set to
True
unless any of the involved methods for one of the arguments is implemented in the current class (i.e. it is not inherited from some base class).So for example by implementing
__eq__
on a class yourself, attrs will deduceeq=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).Warning
If you prevent attrs from creating the ordering methods for you (
order=False
, e.g. by implementing__le__
), it becomes your responsibility to make sure its ordering is sound. The best way is to use the functools.total_ordering decorator.Passing
True
orFalse
to init, repr, eq, order, cmp, or hash overrides whatever auto_detect would determine.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 Exceptions.eq (bool | None) –
If
True
orNone
(default), add__eq__
and__ne__
methods that check two instances for equality.They compare the instances as if they were tuples of their attrs attributes if and only if the types of both classes are identical!
See also
comparison
order (bool | None) –
If
True
, add__lt__
,__le__
,__gt__
, and__ge__
methods that behave like eq above and allow instances to be ordered. IfNone
(default) mirror value of eq.See also
comparison
cmp (bool | None) –
Setting cmp is equivalent to setting eq and order to the same value. Must not be mixed with eq or order.
See also
comparison
unsafe_hash (bool | None) –
If
None
(default), the__hash__
method is generated according how eq and frozen are set.If both are True, attrs will generate a
__hash__
for you.If eq is True and frozen is False,
__hash__
will be set to None, marking it unhashable (which it is).If eq is False,
__hash__
will be left untouched meaning the__hash__
method of the base class will be used (if base class isobject
, 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 also
Our documentation on hashing,
Python’s documentation on object.__hash__,
and the GitHub issue that led to the default behavior for more details.
hash (bool | None) – Alias for unsafe_hash. unsafe_hash takes precedence.
init (bool) –
Create a
__init__
method that initializes the attrs attributes. Leading underscores are stripped for the argument name. If a__attrs_pre_init__
method exists on the class, it will be called before the class is initialized. If a__attrs_post_init__
method exists on the class, it will be called after the class is fully initialized.If
init
isFalse
, an__attrs_init__
method will be injected instead. This allows you to define a custom__init__
method that can do pre-init work such assuper().__init__()
, and then call__attrs_init__()
and__attrs_post_init__()
.See also
init
slots (bool) – Create a slotted class 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 glossary entry.
frozen (bool) –
Make instances immutable after initialization. If someone attempts to modify a frozen instance, attrs.exceptions.FrozenInstanceError is raised.
Note
This is achieved by installing a custom
__setattr__
method on your class, so you can’t implement your own.True immutability is impossible in Python.
This does have a minor a runtime performance impact <how-frozen> when initializing new instances. In other words:
__init__
is slightly slower withfrozen=True
.If a class is frozen, you cannot modify
self
in__attrs_post_init__
or a self-written__init__
. You can circumvent that limitation by usingobject.__setattr__(self, "attribute_name", value)
.Subclasses of a frozen class are frozen too.
weakref_slot (bool) – Make instances weak-referenceable. This has no effect unless
slots
is also enabled.auto_attribs (bool) –
If
True
, collect PEP 526-annotated attributes from the class body.In this case, you must annotate every field. If attrs encounters a field that is set to an attr.ib but lacks a type annotation, an 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 usingattr.ib(default=42)
. Passing an instance of attrs.Factory also works as expected in most cases (see warning below).Attributes annotated as typing.ClassVar, and attributes that are neither annotated nor set to an attr.ib are ignored.
Warning
For features that use the attribute name to create decorators (e.g. validators), you still must assign attr.ib to them. Otherwise Python will either not find the name or try to use the default value to call e.g.
validator
on it.These errors can be quite confusing and probably the most common bug report on our bug tracker.
kw_only (bool) – Make all attributes keyword-only in the generated
__init__
(ifinit
isFalse
, this parameter is ignored).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.auto_exc (bool) –
If the class subclasses BaseException (which implicitly includes any subclass of any exception), the following happens to behave like a well-behaved Python exceptions class:
the values for eq, order, and hash are ignored and the instances compare and hash by the instance’s ids (N.B. attrs will not remove existing implementations of
__hash__
or the equality methods. It just won’t add own ones.),all attributes that are either passed into
__init__
or have a default value are additionally available as a tuple in theargs
attribute,the value of str is ignored leaving
__str__
to base classes.
collect_by_mro (bool) –
Setting this to True fixes the way attrs collects attributes from base classes. The default behavior is incorrect in certain cases of multiple inheritance. It should be on by default but is kept off for backward-compatibility.
See also
Issue #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 andFalse
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 (i.e. not inherited), it is set to False (this is usually what you want).on_setattr (callable, or a list of callables, or None, or 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 likesetattr(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.
field_transformer (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, e.g., to automatically add converters or validators to fields based on their types.
See also
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.
