colour.hints.ClassVar#

colour.hints.ClassVar = typing.ClassVar[source]#

Special type construct to mark class variables.

An annotation wrapped in ClassVar indicates that a given attribute is intended to be used as a class variable and should not be set on instances of that class. Usage:

class Starship:
    stats: ClassVar[Dict[str, int]] = {} # class variable
    damage: int = 10                     # instance variable

ClassVar accepts only types and cannot be further subscribed.

Note that ClassVar is not a class itself, and should not be used with isinstance() or issubclass().
