Python attributes without boilerplate

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 Cobject … x = attr.ibdefault=42 … y = attr.ibdefault=attr.Factorylist i = Cx=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.
