## 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!
|
||
|
|
```
