Isso é especialmente útil durante os testes, já que é bastante simples sobrescrever uma dependência com suas configurações personalizadas.

### O arquivo de configuração

Baseando-se no exemplo anterior, seu arquivo `config.py` seria parecido com isso:

```Python hl_lines="10"

error messages, debug information, and object files. In practice,
parsing these is significantly less work and more robust than parsing
C source.

Cgo first invokes gcc -E -dM on the preamble, in order to find out
about simple #defines for constants and the like. These are recorded
for later use.

Next, cgo needs to identify the kinds for each identifier. For the
identifiers C.foo, cgo generates this C program:

	<preamble>

class ParameterBase(BaseModelWithConfig):
    description: Optional[str] = None
    required: Optional[bool] = None
    deprecated: Optional[bool] = None
    # Serialization rules for simple scenarios
    style: Optional[str] = None
    explode: Optional[bool] = None
    allowReserved: Optional[bool] = None
    schema_: Optional[Union[Schema, Reference]] = Field(default=None, alias="schema")

E nós retornamos os escopos como parte do token JWT.

/// danger | Cuidado

Para manter as coisas simples, aqui nós estamos apenas adicionando os escopos recebidos diretamente ao token.

// it returns the data read before the error and the error itself (often io.EOF).
// ReadBytes returns err != nil if and only if the returned data does not end in
// delim.
// For simple uses, a Scanner may be more convenient.
func (b *Reader) ReadBytes(delim byte) ([]byte, error) {
	full, frag, n, err := b.collectFragments(delim)
	// Allocate new buffer to hold the full pieces and the fragment.

Pero también puedes aprovechar los beneficios del paralelismo y el multiprocesamiento (tener múltiples procesos ejecutándose en paralelo) para cargas de trabajo **CPU bound** como las de los sistemas de Machine Learning.

### **4.2 WordCount**

WordCount is a simple program that counts how often a word occurs in a text file. The code builds a dataset of (String, Int) pairs called counts, and saves the dataset to a file.
