Using attrs for everything in Python

While the conciseness of attrs is nice, it's not very readable. This: class Point3D(object): def __init__(self, x, y, z): self.x = x self.y = y self.z = z ...is much easier to read than this: import attr @attr.s class Point3D(object): x = attr.ib() y = attr.ib() z = attr.ib() Readability is what I love about Python. I don't think the conciseness of attrs is worth the loss in readability.

The @dataclass decorator [1] as proposed in PEP 557 [2] has also been available since Python 3.7 was released in 2018. Using @dataclass the example from OP would look like: from dataclasses import dataclass @dataclass class Point3D: x: float y: float z: float [1]: https://docs.python.org/3/library/dataclasses.html [2]: https://www.python.org/dev/peps/pep-0557/

If I'm not mistaken, python 3.7's data classes will make attrs mostly obsolete?

Actually, I consider the immutability of a `namedtuple` instance to be a benefit. I wish more things in Python were/could be immutable. I have been known to subclass `tuple` from time to time when I want both immutability and the ability to define methods. I wince when I see `namedtuple` being subclassed. Most users don't realise that the implementation of it actually builds up a giant string to pass to `eval()`... thoroughly nasty! At least it's hidden underneath the covers…
