Project Summary

Traitlets is a pure Python library enabling:

the enforcement of strong typing for attributes of Python objects (typed attributes are called "traits");
dynamically calculated default values;
automatic validation and coercion of trait attributes when attempting a change;
registering for receiving notifications when trait values change;
reading configuring values from files or from command line arguments - a distinct layer on top of traitlets, so you may use traitlets without the configuration machinery.
Its implementation relies on the descriptor pattern, and it is a lightweight pure-python alternative of the traits library.
