attrs: Decorator for Python classes with attributes¶
attrs is the Python package that will bring back the joy of writing classes by relieving you from the drudgery of implementing object protocols (aka dunder methods).
Home page: https://www.attrs.org
Equivalent System Packages¶
$ conda install attrs
macports: install the following packages: py-attrs
$ sudo xbps-install python3-attrs
However, these system packages will not be used for building Sage because using Python site-packages is not supported by the Sage distribution; see trac ticket #29023
