Fonction field - module dataclasses

Signature de la fonction field

def field(*, default=<dataclasses._MISSING_TYPE object at 0x0000020DB9F38C20>, default_factory=<dataclasses._MISSING_TYPE object at 0x0000020DB9F38C20>, init=True, repr=True, hash=None, compare=True, metadata=None, kw_only=<dataclasses._MISSING_TYPE object at 0x0000020DB9F38C20>) 

Description

help(dataclasses.field)

Return an object to identify dataclass fields.

default is the default value of the field.  default_factory is a
0-argument function called to initialize a field's value.  If init
is true, the field will be a parameter to the class's __init__()
function.  If repr is true, the field will be included in the
object's repr().  If hash is true, the field will be included in the
object's hash().  If compare is true, the field will be used in
comparison functions.  metadata, if specified, must be a mapping
which is stored but not otherwise examined by dataclass.  If kw_only
is true, the field will become a keyword-only parameter to
__init__().

It is an error to specify both default and default_factory.
