 🪄 🌟 pretty-match 





  

    

  

  

    

  



A set of utils to be used with match-case statements.

```python

from pretty_match import results

from pretty_match.attrs import FirstNoneAttr, AttrIsNone

from pretty_match.comparable import Number

user = User(balance=1500)

product = Product(price=150)

match Number(user.balance).compare(product.price):

    case results.Less:

        raise NotEnoughMoney

    case results.Greater | results.Equal:

        process_transaction(user, product)

query = Query(token='test', start=None, end=2)

attrs_to_check = ['token', 'start', 'end']

match FirstNoneAttr(*attrs_to_check, instance=query):

    case AttrIsNone(name='token'):

        print('token required!')

    case AttrIsNone(name='start'):

        print('start required!')

    case AttrIsNone(name='end'):

        print('end required!')

```
