development and has changed the mental model used at Enthought for
programming in the already extremely efficient Python programming
language.
The Traits project allows Python programmers to use a special kind
of type definition called a trait, which gives object attributes
some additional characteristics, such as Initialization, Validation,
Delegation, Notification and Visualization.
A class can freely mix trait-based attributes with normal Python
attributes, or can opt to allow the use of only a fixed or open set
of trait attributes within the class. Trait attributes defined by
a classs are automatically inherited by any subclass derived from
the class.
