# swytch

If you've ever felt like you really, really need a switch statement in Python, then this might be the thing for you.

There's a little bit of everything for everyone: Exhaustive switches, default cases, switch cases for hashable types, switch cases for unhashable types, context-based switches, and switches over enums.

```python

import enum

from xswitch import case, Default, ExhaustiveSwitch

class PowersOfTwo(enum.IntEnum):

  zero = 1

  one = 2

  two = 4

  

class PowersOfTwoSwitch(ExhaustiveSwitch, enum=PowersOfTwo):

  @case(PowersOfTwo.zero)

  def zero(self):

    print("2^0")

  

  @case(PowersOfTwo.one)

  def one(self):

    print("2^one")

  

  @case(Default)

  def default(self):

    print("2^?")

if __name__ == "__main__":

  PowersOfTwoSwitch.match(0)

  PowersOfTwoSwitch.match(PowersOfTwo.one)

  PowersOfTwoSwitch.match(5)

>>> 2^0

>>> 2^one

>>> 2^?

```
