__init__(self: LeftAction, generators: list[Element] = None, seeds: list[Point] = None) → None

Construct an Action from generators and seeds, ImageLeftAction and side.left.

Keyword Arguments:

  • generators (list[Element])– at least one generator for the action.

  • seeds (list[Point]) – at least one seed point for the action.

Important

The class LeftAction has all the methods of the Runner class but, for boring technical reasons, is not a subclass of Runner. If thing is an instance of LeftAction, then you can use thing as if it were an instance of Runner but isinstance(thing, Runner) will return False.
