A Value List can be used for Boolean data types. For Boolean data types, the Value List contains two values: true and false. The true value is always the first value in the list. The values specified in the Value list are used in Python for specifying the value. See, for example,...
This means, not only can we use objects, but we can define our own classes of objects. A class is just another name for a type in Python. We have been working with types (i.e. classes) since the first chapter of the text. Examples of classes are int , str , bool , float and ...
A namedtuple-style library for defining immutable sum types in Python. (Get it on PyPI)You may know sum types under a different name – they're also referred to as tagged unions, enums in Rust/Swift, and variants in C++. If you haven't heard about them yet, here's a nice ...
If a tooltip is specified, that tooltip is the name shown in the Customize User Interface dialog. If a tooltip is not specified,<name>is the name shown. Unlike other similar constructs (Scripted Utilities, Functions, and right-click menus),macroScriptdoes not create a variable with this name...
