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 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.
