## Classes como dependências

Você deve ter percebido que para criar um instância de uma classe em Python, a mesma sintaxe é utilizada.

Por exemplo:

```Python
class Cat:
    def __init__(self, name: str):
        self.name = name


fluffy = Cat(name="Mr Fluffy")
```

Nesse caso,  `fluffy` é uma instância da classe `Cat`.

E para criar `fluffy`, você está "chamando" `Cat`.

        self.query(
          '{{type}}',
          sum(irate('pilot_xds_pushes'), by=['type'])
        ),

      xdsErrors: [
        self.query(
          'Rejected Config ({{type}})',
          sum('pilot_total_xds_rejects', by=['type'])
        ),
        self.query(
          'Internal Errors',
          'pilot_total_xds_internal_errors'
