It does this by seeing if the type of a field is. slots__ = ("__name", "__sex", "__age") @[HOST]ctmethod def __init__(self, name, sex="F", age=21): self. A field is defined as a class variable that has a type annotation. Perhaps one of the most important structures of the Python object system is the structure that defines a new type: the PyTypeObject structure. __slots__: Sin usar __slots__: class MiClase(object): def __init__(self, nombre, identificador): [HOST] = nombre [HOST]ficador = identificador self. __sex = "F" if. class Stock: __slots__ = ('name','_shares','price') def __init__(self, name, shares, price): [HOST] = name. Another place where dataclass() inspects a type annotation is to determine if a field is an init-only variable. [HOST] › c-api › typeobj. init__(self,parent=None): super().
