Hi Indian Pythonista,
thanks for these great tutorials on dataclasses.
For an assignment, I have to set each class variable to None if it is equal to "_".
How would you do that nicely? The only thing I've come up is to use __post_init__ and then check each class variable if it is "_" and then change accordingly. However, there are many class variables so I would like to do it more concisely.
Thanks!

Does __post_init__ replace property decorator?

Hi, Why can't you use default_factory field function instead of post_init_processing ? I understand that default_factory field function doesn't take any arguments, but can't it refer to the co properties of the class to replace post_init_processing ?
