Examples

Creating a simple machine

from automaton import machines m = machines.FiniteMachine() m.add_state('up') m.add_state('down') m.add_transition('down', 'up', 'jump') m.add_transition('up', 'down', 'fall') m.default_start_state = 'down' print(m.pformat())

Expected output:

Start	Event	End	On Enter	On Exit
down[^] up	jump fall	up down	.	.

Transitioning a simple machine

m.initialize() m.process_event('jump') print(m.pformat()) print(m.current_state) print(m.terminated) m.process_event('fall') print(m.pformat()) print(m.current_state)

Expected output:

Start	Event	End	On Enter	On Exit
down[^] @up	jump fall	up down	.	.
