- ## Example
- Signal receivers can subscribe to specific senders or receive signals
- sent by any sender.
- ```pycon
- >>> from blinker import signal
- >>> started = signal('round-started')
- >>> def each(round):
- ... print(f"Round {round}")
- ...
- >>> started.connect(each)
- >>> def round_two(round):
- ... print("This is round two.")
- ...
- >>> started.connect(round_two, sender=2)
- >>> for round in range(1, 4):
- ... started.send(round)
- ...
- Round 1!
- Round 2!
- This is round two.
- Round 3!
- ```
