devel/py-attrs 25.3.0 DragonFly

attrs is an MIT-licensed Python package with class decorators that ease the chores of implementing the most common attribute-related object protocols:

>>> import attr >>> @attr.s ... class C(object): ... x = attr.ib(default=42) ... y = attr.ib(default=attr.Factory(list)) >>> i = C(x=1, y=2)

(If you don't like the playful attr.s and attr.ib, you can also use their no-nonsense aliases attr.attributes and attr.attr).

You just specify the attributes to work with and attrs gives you:

a nice human-readable \_\_repr\_\_,
a complete set of comparison methods,
an initializer,
and much more

without writing dull boilerplate code again and again.
