# Blinker

Blinker provides a fast dispatching system that allows any number of

interested parties to subscribe to events, or "signals".

## 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!

```
