Frequently Asked Questions

Where does Python store default member variable values?

Python stores default member variable values in class attributes. Consider this example, not using dataclasses: Note that the two instances of class C share the same class variable x, as expected. This has the same issue as the original example using class C .

Is it possible to set default values for default fields in Python?

However, this is not valid Python. If a parameter has a default value, all following parameters must also have a default value. In other words, if a field in a base class has a default value, then all new fields added in a subclass must have default values as well. Another thing to be aware of is how fields are ordered in a subclass.

Classes ¶.

Objects can contain arbitrary amounts and kinds of data.
