![]() ![]() These compare the class as if it were a tuple of itsįields, in order. ![]() Order: If true (the default is False), _lt_(), If the class already defines _eq_(), this parameter is This method compares the class as if it were a tuple If the class already defines _repr_(), this parameter isĮq: If true (the default), an _eq_() method will be InventoryItem(name='widget', unit_price=3.0, quantity_on_hand=10). Fields that are marked as being excluded from the repr The name and repr of each field, in the order they are defined in The generated repr string will have the class name and Repr: If true (the default), a _repr_() method will be If the class already defines _init_(), this parameter is Init: If true (the default), a _init_() method will be ( init = True, repr = True, eq = True, order = False, unsafe_hash = False, frozen = False, match_args = True, kw_only = False, slots = False ) class C. That is, these three uses of dataclass() class C. It acts as if it has the default values documented in this If dataclass() is used just as a simple decorator with no parameters, The decorator returns the same class that it is called on no new If any of the added methods alreadyĮxist in the class, the behavior depends on the parameter, as documentedīelow. The dataclass() decorator will add various “dunder” methods to Order in which they appear in the class definition. The order of the fields in all of the generated methods is the A field is defined as a class variable that has aĮxceptions described below, nothing in dataclass()Įxamines the type specified in the variable annotation. The dataclass() decorator examines the class to findįields. Special methods to classes, as described below. This function is a decorator that is used to add generated dataclass ( *, init = True, repr = True, eq = True, order = False, unsafe_hash = False, frozen = False, match_args = True, kw_only = False, slots = False ) ¶ ![]()
