## 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! |
|
``` |
